FATAL ERROR in native method: Non-array passed to JNI array operations
After stepping up to JDK 1.4.2 we started getting a hotspot error, I added -Xcheck:jni and it yielded the above error which was not existent in JDK 1.4.1 and for the life of me I cannot find out whats wrong:
Native method dec:
private native byte[] cost(final byte[] byte_array,
final double minCostPerMeter,
final int costFuncSelection,
final double maxCostThreshold);
Method call:
ByteArrayInputStream
inputByteStream = new ByteArrayInputStream(
cost(output_byte_stream.toByteArray(),
minCostPerMeter,
costFunctionSelection.length,
maxCostThreshold));
An array is being passed I have no idea why it is complaing about the method call.
Any help would be appreciated.

What happens if you remove all the code from the JNI method - so it just calls and then returns?
If it still occurs then I would expect that you have a memory problem in a piece of code before this one. Such problems can have no impact when run in one environment but cause failures in another becomes some other legitimate piece of data moved.
If it doesn't then I would expect that the problem is in the method itself and not the call.
It could be some odd VM problem so trying a different version of 1.4.2 might help (but in of itself would not eliminate the possibility that you have a memory problem.)

Error: Non-array passed to JNI array operations
Can anyone see what I am doing wrong? I am trying to go through the array of objects example in the online JNI text book "The Java Native Interface Programmer's Guide and Specification" by Sheng Liang. The book and pertinent chapter can be found here:
http://java.sun.com/docs/books/jni/html/objtypes.html#27791
The error I received on running the program with the -Xcheck:jni switch is this:
FATAL ERROR in native method: Non-array passed to JNI array operations
at petes.JNI.ObjectArrayTest.initInt2DArray(Native Method)
at petes.JNI.ObjectArrayTest.main(ObjectArrayTest.java:14)Without the xcheck switch, I get a huge error log file that I can reproduce here if needed.
My c code with #ifdef _Debug statements removed for readability is listed below. The location of the error (I believe) is marked:
#include <jni.h>
#include <stdio.h>
#include "petes_JNI_ObjectArrayTest.h"
//#define _Debug
// error found running the program with the -Xcheck:jni switch
//page 38 and 39 of The Java Native Interface Guide by Sheng Liang

}Here is my java code

private static native int[][] initInt2DArray(int size);

System.loadLibrary("petes_JNI_ObjectArrayTest");
public static void main(String[] args)

if (i2arr != null)
for (int i = 0; i < i2arr.length; i++)
for (int j = 0; j < i2arr[0].length; j++)
System.out.println(" " + i2arr[i][j]);
System.out.println();
else
System.out.println("i2arr is null");
}Thanks in advance!
PeteNiceguy1: Thanks for the quick reply!
So far, I mainly see the usual differences between C and C++ JNI calls. Also, in the example you gave, they use a lot of casts, but that doesn't seem to make much difference to my output. Also, in the example, they create a 0-initilized int array, and use this class to initialze the class type of the Object array. I get the class type by a call to FindClass for a class type of "[I". I'll try this their way and see what happens...
Edit: Changing the way I find the array element Object type did not help. I still get the same error as previous. Any other ideas would be greatly appreciated.

FATAL ERROR in native method: Wrong Method ID
I have a piece of C code from which I am trying to launch a piece of Java, but I am having severe problems just trying to get a simple integer value returned from any Java function. I keep getting the error message "FATAL ERROR in native method: Wrong method ID used to invode a Java method"
My C code looks like :
JNIEnv *env;
long result;
jmethodID mid;
jclass cls;
jobjectArray args;
jstring jstr;
jint res;
jobject myObj;
options[0].optionString = "-Djava.class.path=.";
options[1].optionString = "-Djava.compiler=NONE";
options[2].optionString = "-verbose:jni";
vm_args.version = JNI_VERSION_1_2;
vm_args.options = options;
vm_args.nOptions = 2;
vm_args.ignoreUnrecognized = JNI_FALSE;
// Create the Java VM
result = JNI_CreateJavaVM(&jvm,(void **)&env, &vm_args);
if (result == JNI_ERR )
printf("Can't create Java VM\n");
exit(1);
else
printf("Java VM created successfully\n");
cls = (*env)->FindClass(env, "Example1");
if (cls == 0){
printf("Can't find Class\n");
exit(1);
else
printf("Class Found\n");
mid = (*env)->GetMethodID(env, cls, "GetIntValue", "()I" );
if (mid == 0) {
printf("Can't find function\n");
exit(1);
else
printf("Function Found\n");
res = (*env)->CallIntMethod(env, cls, mid);
if (res != 0)
char pszTempString[256] = {'\0'};
sprintf (pszJavaString, "Returned from Java the value of %d", res);
printf("Returned from Java with ");
printf(pszJavaString);
My GetMethodID call works correctly and I have checked the signature (using javap -s) and that works fine. I've seen many references on these forums about using NewObject prior to calling CallIntMethod, but if I try to use that I then get the error message "FATAL ERROR in native method: a non-constructor passed to NewObject".
Any body got any ideas please.
ThanksWhat I couldn't figure out from your code is where you create the java object that is supposed to return the integer to your C code.
Alternatives:
o This is just code snippets, and you really are creating the object.
o Error - the object should have been created.
o Error - it is a static method, and you should be finding a static method and calling it on a class object.
(Other than that, I didn't see anything obviously wrong. -
Dear all,
I am working on a MacOSX. I am having trouble in using a Dynamic Library generated from C files and accessed from a java project using JNI.
The loading of the library work well bur when i try to access a method I have the following error:
FATAL ERROR in native method: JNI received a class argument that is not a class
at cytosolve.sbmlSolver.SBMLSolver.initSolver(Native Method)
at cytosolve.sbmlSolver.SBMLSolver.<init>(SBMLSolver.java:87)
at cytosolve.sbmlSolver.cytosolve.main(cytosolve.java:29)where the Native method inside the C file is the following:
JNIEXPORT jint JNICALL
Java_cytosolve_sbmlSolver_SBMLSolver_initSolver(JNIEnv *env, jobject obj, jstring model_filename, jdouble totalTime, jint numSteps)and it is called from the Java file as:
int successCode = initSolver(model_filename, totalTime, numSteps);Do you have any idea on where is the problem and how to fix it?
Thank you,
Eva.Everything seems to be right. Maybe you use JNI functions inproperly?

Forte debugger exits (FATAL ERROR in native method: JDWP "util.c")
When debugging my GUI app in Forte on Solaris 8, my debug session exits with the following error:
FATAL ERROR in native method: JDWP "util.c" (Feb 20 2002), line 1029: Unexpected error, error code = 113 (JVMDI_ERROR_INTERNAL)
It seems to do so while in the middle of a comm api routine where I'm accessing the serial port. Has anyone else ever seen this error is Solaris? I have all of the patches required by Sun for JDK1.3.1_02 installed with the same version of the JDK.
The application runs fine when I run it standalone...
Any suggestions?
Thanks.I've had the same problem. It appears that it occures when an error is thrown that stop a JSP page load.
Everything will run find up to that point, but after that, the util.c error will not go away except by deinstall and reinstall of Forte. We can't even use Forte at this point since it will start throwing the error within 1 hour of reinstall. Crap.
I'm on Windows XP also, and this happens with JVM 1.3 or 1.4. -
FATAL ERROR in native method: JNI call made with exception pending
Hi everyone,
I am trying to resolve this error exhaustively for the last 3 days.
I have a 3rd Party DLL library which i am supposed to use from my Java Application. I compiled my own DLL that links(calls methods) the Java code and the the 3rd party DLLs.
It works fine in my machine and 2 of my other colleagues but does work for the QA tester. The JVM crashes when it comes to the point of loading the DLL with the exception mentioned above.
For the QA tester, a version of the DLL made in VC7.1 works fine, but the one we are trying to load was made in VC80.
It also has the dependency dll like msvcr80.dll and msvcp80.dll
We both have Windows XP and same the JVM (1.4)
Please Help !!!!!!!
Thanks,
ZuberI would suggest further investigation of dependencies. If the QA machine doesn't have VC 8 check what the diffs are there.

ERROR_WAIT_NO_CHILDREN error while native method calling
I have some self-made DLL and call it from Java over JNI.
Under 100% repeatable conditions, the calling of the native method conduce to
java.exe(JVM) termination with errorlevel 128L. Without any trace or reports.
If to assume, that java.exe uses OS error codes, then 128L is
'ERROR_WAIT_NO_CHILDREN - There are no child processes to wait for.'
What that? JVM crashed by the Dll?
Some additional information:
I found the position(approximately) in C code where the execution is stopping.
It far from JNI/C function declaration.
Dll is compiled by Watcom C/C++32 Compiler and Linker, Version 11.0.
I tried to compile Dll by Borland C++ 5.5.1 free command-line compiler, and error
disappears. But I don't think it right way to refer the error to compiler.
And something else. Native code work fine, if it was called not from Java but
from native application.
Any ideas?
Thanks.Hmm, could You send the header of the method from Your
DLL which you are calling from Java?Sure.

However if you failed to load the library then you cannot get the error that you posted unless you are ignoring the exception from the load() call. And doing that is a bad idea.
At least if the library is not loading.
If it is loading then the method that you use to load it has nothing to do with your problem. -
How call native method without code modification
"How to access third party's C API from Java Using JNI without modifying the C code"
Unfortunately, the only way I know of doing this is to use a pass-through DLL that you write. Logically it
looks like this:
Java App (written by you)
|
v
Java native methods (written by you)
|
v
JNI DLL (written by you)
|
v
3rd party DLL
It adds a little bit of overhead, but it's not too big of a deal. Check out the JNI tutorial on how to write this.

Testing ActionScript classes with native methods?
Hi,
I have an ActionScript class that I'm writing and would like to test using FlexUnit.
The only issue is that the ActionScript class has a member in it that is a class with native methods.
So, I get the following error when trying to run a test of that ActionScript class:
VerifyError: Error #1079: Native methods are not allowed in loaded code.
Does anyone know of a way to get around this? FlexUnit seems not to like native methods being present.
Thanks,
MattHi casdvm,
by definition, you only own objects that you created using one of the alloc* methods, copy: or new:. All other objects (IIRC with a few noted exceptions) are autoreleased.
If you create convenience methods in your own class, you should follow the same rule. For example, if you have a class Pet and want to implement the method +petWithName, your code might look something like that:
+ petWithName: (NSString *)name
return [[[Pet alloc] initWithName: name] autorelease];
