JVM crashing due to JNI call

Hi All
My application uses JNI to interact with other classes developed in C++. When I run the application ,which is comiled in java1.4, against java 1.5 ,it is crashing for any operation related to JNI. When I run the application with -Xint JVM option it worked fine. What is this Xint all about ..
Thanks in advance

Most likely, you are holding on to a reference back into Java's managed memory that you should not be. The JIT is moving things around to optimize them (and 1.5 is probably doing other optimizations that 1.4 wasn't).
Even if your app runs under 1.4, or with the JIT disabled under 1.5, it is not implemented properly. Are you properly releasing all array references on the JNI side? Are you managing threads properly?
What exactly are you doing in the JNI code? Have you tried attaching a debugger to the native code to see exactly what is crashing? Worst case, but a bunch of print statements in there and run the Java app in a console so you can see the output...

Hi Folks:
You are right . Using -Xint will not crash the JVM in
Java 1.5. I too had the same problems.
Well by using -Xint we are switching off the Just in
Time compilation in HotSpot VM . So everything will
be interpreted rather then being compiled to native
code at run time. But I really dont know whats
happening in Java 1.5 because my program is running
fine in with Java 1.4.02 without using -Xint option.

  • JVM Crash When Using JNI and COM

    I'm trying to call a DLL compiled from VB6 source code that I do not have access to. The VB6 code simply retrieves data from a DB2 database using ADO and my client code grabs that data and marshals it to my Java code. I'm attempting to achieve this using JNI and COM (without a third-party bridge). It works 75% of the time, but the other 25% of the time, the JVM crashes with the usual Hotspot crash log containing an access violation exception. However, I don't know what in my C++ code (VC++ 8) could be causing this except for passing a "wild" pointer to the code lying underneath the COM object interface. If that is the case, I don't know how I am doing that.
    The Java code that is calling my native method is running on Tomcat 5.5.25 and just to be safe, I am not allowing multiple threads to concurrently call the method in my JNI DLL (though I realize that this will kill performance). Once I can get past this problem, I'll do the COM interfacing on a worker thread in my native code so I don't screw up CoInitialize and CoUninitialize calls in the case the same thread is concurrently executing multiple calls to my native code.
    I've noticed that in most cases, the JVM crashes during my call to the pClsAccount->OpenConnection method. However, my DLL isn't what is listed on the top of the call stack, which is why I suspect the passing of a wild pointer, though I'm just taking a guess at that. Does anyone have an idea as to what's going on ?

  • Tomcat/Websphere JVM Crashes due to JCO / sapjcorfc.dll

    We have developed a web application on Tomcat/Websphere that uses JCO to connect to SAP/R3 and request data.

    For me it looks like a memory problem on the JNI layer... but my JVM have sufficient memory(1GB) and there is left another GB free Mem.
    Any ideas what to do would be helpful.

    Kitten,
    RAM 1GB is not mean that you have free space. Just do garbage collecting before processing. What I mean is break your records recording in such a way that, at a time you read only 50% of crashing capacity

  • JVM Crashes due to memory shortage ...

    I have a Java application which runs as a server on my Windows 2000 Server machine having 2GB RAM and virtual memory specified as 2-4GB. I start the application with the options -Xms786m -Xms-786m.
    I have around 1500 clients that connect to this server and I open 2 dedicated server sockets for each client. The clients keep sending reuests over these connections for which they get the response over these connections. I connect to an Oracle database using the oracle 'thin' driver for this.
    Till recently everything was running fine until I made some very small changes such as addition of some 50-100 users and a few more request-response sets due to which I have run into trouble. My server keeps crashing as soon as it gets around 1600 clients and the memory used by the process reaches around 2GB(seen through Perfmon). Sometimes I get the error :
    Exception in thread �main� java.lang.OutOfMemoryError: request <size> bytes for <reason>. Out of swap space
    and sometimes the jvm terminates without any error/message.
    I also profiled the server but there dont seem to be any problems with the objects on the heap. I know that this is because I am running short of native heap memory. How can I identify what is causing this and is there any way to increase this limit ?

    Did you mean you use -Xms786m -Xmx786m?
    If so, did you try increasing that to -Xms1024 -Xmx1024?
    I thought I read somewhere that there is a ultimate limit of 2G for JRE on 32-bit Windows.
    I would say that ultimately, if you find there is a JRE memory limitation that prevents a single JRE from using all available system memory, that you could always split your application into several separate JRE's that communicate with each other using the best interprocess service available. Split your app into an upper tier to handle all the client setup/teardown and a lower tier to handle other stuff. Or maybe some other logic split that works better for your application/design.

  • JVM Crash while using JPAM in SUSE 10.1 Linux

    Hi,
    I had done the necessary settings as specified in the manual to setup JPAM. when i access from my Java program, im getting the following error messages,
    # An unexpected error has been detected by HotSpot Virtual Machine:
    # SIGFPE (0x8) at pc=0xb7f9326b, pid=3886, tid=3085153968
    # Java VM: Java HotSpot(TM) Client VM (1.5.0_15-b04 mixed mode, sharing)
    # Problematic frame:
    # C [ld-linux.so.2+0x926b]
    # An error report file with more information is saved as hs_err_pid3886.log
    # If you would like to submit a bug report, please visit:
    # http://java.sun.com/webapps/bugreport/crash.jsp
    in order to check the flow, i just commented the System.LoadLibrary( ); call in the Pam.java file of JPAM, the flow works fine.
    So, the JVM crash happens during Native call.
    The error log is as follows ,
    # An unexpected error has been detected by HotSpot Virtual Machine:
    # SIGFPE (0x8) at pc=0xb7f2b26b, pid=4325, tid=3084727984

  • Java.lang.Class- getFields() results in JVM crash when called through JNI

    From a C++ application, I use Invocation APIs to create a JVM and call some Java methods using JNI
    I get a crash in jvm.dll with EXCEPTION_ACCESS_VIOLATION
    when I try to call "getFields" method of java.lang.Class in order to get the Fields of the java class
    This method call, should return a java/lang/reflect/Fields[] on success
    I am able to get the method ID of this method by using pEnv->GetMethodID(..)
    However, when I call this method using CallObjectMethod(..), HotSpt JVM crashes with access violation with the dump given below.
    Any clues on how to debug and find the problem?
    Or has anyone tried getting the fields of a Java class from C++ by calling reflection APIs uing JNI?
    Thanks in advance!
    Sample code
    jclass testerClass = pEnv->FindClass("com/test/Tester");
    jmethodID cid = pEnv->GetMethodID(testerClass,"<init>","()V");
    if(NULL == cid)
    pEnv->ExceptionDescribe();
    jobject testerObject = pEnv->NewObjectV(testerClass, mid);
    jmethodID mid = pEnv->GetMethodID(testerClass, "getClass",
                             "()Ljava/lang/Class;");
    jobject clsObj = (jobject)pEnv->CallObjectMethod(testerObject, mid);
    pEnv->ExceptionDescribe();
    jclass      jCls = pEnv->GetObjectClass(clsObj);
    jmethodID midGetFields = pEnv->GetMethodID(jCls, "getFields",
                                            "()[Ljava/lang/reflect/Field;");
    jobjectArray jobjArray = (jobjectArray)pEnv->CallObjectMethod(testerObject, midGetFields);

    You are right, I tried getting the java.lang.Class reference for the com.test.Tester by calling getClass() on com.test.Tester
    And using this jclass reference for java.lang.Class, I tried getting the method ID of getFields and eventually the Field[]
    Thanks for the help
    I have some more questions.
    Assumption - Using JNI, I got the fields array of com.test.Tester and I am iterating through the fields
    1.Assuming that the Tester class had an Integer field say m_nIntVal, then once I get the jobject equivalent of this Field in C++.
    Now I need to get the type of the field (I call the method java.lang.reflect.getType() from JNI)
    This gives me a jclass reference to it's type i.e java.lang.Integer
    2.I need to get the name of this type i.e I want to get the name of the type in a string as "java.lang.Integer"
    For this, on the jclass reference of java.lang.Integer got in Step 1, I call getClass() from JNI (to get the java.lang.Class) and then getName()
    Now, for calling getClass(), I need a temporary object reference corresponding to the jclass of java.lang.Integer, The problem is that Integer does not have a default constructor, so my call to create the jobject fails.
    But, since I do not know that I am constructing an Integer (remember that is what I am trying to find out - getType), I cant pass any values to constructor
    Now, how do I go about creating a jobject of Integer, without knowing that I am constructing that, as this does not have a default constructor without parameters
    Also, I tried using AllocObject to get the jobject and then tried to get the method ID of getClass(). Even this failed
    3. If the com.test.Tester class had a primitive "int" field, say m_nPrimitiveInt
    for which java provides a Class representation, I am able to get the jclass reference to the type of m_nPrimitiveInt
    Now, how do I get the name of the type as "int" in a string?
    Forllowing a similar procedure like in Step 2 fails when I try to pass the jclass reference to the type of m_nPrimitiveInt to the GetMethodID
    with the error FATAL ERROR in native method: JNI received a class argument that is not a class
    Can you tell me what is the way out?
    Thanks in advance,
    Also, can I mail you with some doubts that I have? If its ok, please contact me at [email protected]

  • Variety of periodic JVM crashes (no JNI)

    Hello,
    I have a J2SE application that runs on a Linux box that is getting a number of various JVM crashes. The program has no JNI and does not use any libraries, it's all just Java. The call stacks are always different, and I don't see any consistency in what is happening in the application when the JVM crashes. It does however always seem to be a SIGSEGV. Sometimes they happen after 2 minutes of uptime, sometimes after days.
    I tried upgrading the JVM from 6.0_27-b07 to 7.0_06-b24 but it has made no difference. I uploaded all the hs_err logs here: http://www.tacticstudios.com/downloads/logs.rar if you would like to take a look.
    Due to the inconsistent call stacks my only assumption is that memory is getting corrupted in some way, and the crash is occurring later on.  Maybe it is a hardware problem? I'm not certain what would cause this.
    Any assistance you can provide in how to debug this, or any ideas would be extremely appreciated. I have pasted the most recent error log below.

    Hi!
    I've got the jvm crashing when it calls native methods
    via the JNI.
    The same native method run without a glitch in "pure"
    C. So there is no bug in the native method, I suppose.
    What is more interesting
    is that the same java program with the same native
    interface runs fine using gij (from gnu) too!

    Abhishek.Signal 11 is a segmentation fault. If this runs fine in pure C then you may be passing it a null value on the Java side. I am unfamilar with gij, so I don't know what to say about that

  • Debugging JVM crash via JNI Invocation

    Our software is causing a JVM crash with an EXCEPTION_FLT_STACK_CHECK error using the latest
    Sun 1.4.2 and 5.0 JVMs on Windows XP. No such error appears with 1.4 on Macintosh OS X.
    We start the JVM via JNI Invocation - our software is a plug-in for a standard Windows GUI program that
    requires a C++ interface. How can we get a crash dump or otherwise see what is going on when we
    crash? We don't have a chance to catch a Java exception. It seems to be crashing within a very generic
    call to the Xerces 2.6.2 XML parser.
    When we use the "-XX:+ShowMessageBoxOnError" option invoking the JVM, we do see a message box
    on the JVM error. Using the "-Xcheck:jni" option shows no problems. I tried viewing the JVM in jconsole,
    which worked nicely, but adding the "-Dcom.sun.management.jmxremote" option makes the crash
    go away.
    I feel like I've likely missed something obvious in my web and reference searches, but on the other hand
    JNI invocation information can be in short supply. This bug is 100% reproducible with a certain software
    and data setup.
    Thanks for any pointers and advice you can offer!
    Michael

    Thanks. Off list someone also pointed me to the Java troubleshooting guide at:
    http://java.sun.com/j2se/1.5/pdf/jdk50_ts_guide.pdf
    This is very helpful for giving instructions for creating a crash dump. Sun might be able to use it but I can't
    seem to get any response to my JVM bug report, so I'm looking for something that might help me figure
    out what the heck is going on. Is there a way to get a normal Java fatal error log via either
    -XX:+ShowMessageBoxOnError or -XX:OnError?
    Thanks again,
    Michael

  • JNI Calling Java code when attaching to existing JVM

    I've got an Active/X that runs within IE, and also makes JNI calls (via the Invocation API) to Java code. Running within IE means there's already a JVM around, so I attach to it using JNI_GetCreatedJavaVMs
    This is fine. The problem is that I can't use the JNI findClass() to locate my Java classes, because I have no control over the classpath that the JVM is using to locate classes. The only solution I can think of so far is to either add my classes as part of the JVM, OR find out the classpath of the existing JVM (using System.getProperty("java.class.path") and copy my classes into that directory.
    Both solutions look ugly - anyone know of a cleaner way ?
    Mark.

    Toby, thanks for the reply.
    You're welcome.
    I notice from elsewhere on this forum, you're clearly a JNI expert.
    I've been known to work with it a little from time to time. =)
    My code has to work with JDK 1.1 so URLClassLoader is out. Writing my own classloader is fine, but how do I load it in the first place ? Is there something in JNI I've missed ?
    Possibly. Using DefineClass() you can load a class into the virtual machine, given it's byte-code. Now here's the tricky part. First, write your ClassLoader. It will be easiest if it doesn't rely on any other classes other than what is core to the JRE. Once you compile that classloader, you then need to include the bytecode as a resource in your executable/dll. Then, at runtime, you can load that resource, and use DefineClass to class-load it. Once you've class-loaded it, you can use NewObject, GetMethodID, CallXXXMethod, etc... to do the other class loading you need to do.
    Trust me, this really isn't as hard as it might sound.
    God bless,
    -Toby Reyelts
    As always, I recommend you check out the free, open-source JNI toolkit, Jace, at http://jace.reyelts.com/jace.

  • Creating JVM to Make JNI calls

    I am trying to create a JVM to make JNI calls to Java. When I try to link my C++ program with jvm.lib, I am getting following error. Please advise.
    "fatal error LNK1106: invalid file or disk full"
    I am sure the disk is not full.

    What IDE are you using? I am using MS VC++ 5.0 with jdk 1.3 and I got the same error. After trying several things (including recreating my project)I realized that jdk 1.3 was created after VC++ 5.0. So on a wild hunch I installed jdk 1.2.2. I then removed all project referrences to jdk 1.3. Closed all my files. Reopend them. Made sure the jni.h external dependency was pointing to 1.2.2 (you may have to do a build to force it) and then everything linked fine.

    Any idea how to solve this issue will be greatly appreciated.
    Thank you.

    This deffinition ( __declspec(thread) ) of the thread local veriable does not works in some cases (see articles in MSDN how to define thread local variables in C++ code). JVM loads your native module (DLL) with LoadLibrary function. This is one of the cases when __declspec(thread) is wrong in C++ code.

  • Application crashes when using JNI with Jdk 1,2, 1.3 and 1.4

    Hi!
    I have this application that has a GUI written in Java and a file parser written in C. JNI is used to connect these parts together. The problem is that the application only works when I am using jdk 1.1.8 but not when using jdk1.2, jdk1.3 or jdk1.4. I am running the application on a Solaris 8 machine.
    I have not written the application myself but I am going to be working with it from now on. But I have today little knowledge with JNI and I have tried different approaches to solve the problem. For example I have tried to used DDD together with GDB to find out what the problem is but with no luck. When I run the application using jdk1.4 I get the following error when the JVM crashes:
    An unexpected exception has been detected in native code outside the VM.
    Unexpected Signal : 10 occurred at PC=0xFA023164

    From this information I think that the problem should be in the native method setDebug. But I have tried to set a breakpoint at the beginning of that function in the C part but with no luck. The application crashes before it reaches that position in the C file.
    What could possibly go wrong between the setDebug function in the C part and the function call in the Java part?
    When using GDB, GDB cannot figure out what is wrong it just returns a hex address, no function name.
    I would really appreciate some help. I have tried everything that I can come up with!
    Best regards

    I have figured out that the application fails on its first call to the native methods.
    So I have this Bitmap class that contains all the native calls and it is defined shortly as follow:
    public class Bitmap {
    static {
    System.loadLibrary("BitmapImpl");
    native void setDebug(int debuglevel, int statistics);
    There are many more native methods defined in Bitmap, but I only show the setDebug method because that is the first one that is executed and also the one that immediately fails.
    My setDebug C function is defined as follow in BitmapImpl.c
    #include <time.h>
    #include <stdio.h>
    #include <limits.h>
    #include <fcntl.h>
    #include <jni.h>
    #include <math.h>
    #include <errno.h>
    #include "Bitmap.h"
    #include "data.h"
    jint debug = 0;
    jint statistics = 1;
    JNIEXPORT void JNICALL Java_Bitmap_setDebug
    (JNIEnv *jenv, jobject jo, jint d, jint s)
    debug = d;
    statistics = s;
    My libBitmapImpl.so file is compiled using the following Makefile and using GNU gcc:
    JAVAPATH=$(JAVAINCLUDEPATH)
    LMACRO=-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DSOLARIS
    CSOURCE=BitmapImpl.c
    all:
    gcc -O3 -G $(LMACRO) -I$(JAVAPATH) -I$(JAVAPATH)/solaris \
    $(CSOURCE) -o libBitmapImpl.so
    It is still a total mystory why the application fails. I have tried it on a RedHat Linux machine and there it works fine. But not on Solaris. Only if I use the jdk1.1.8 but not a later one.
    Would really appreiciate some help!
    Best regards
