JVM crash when calling no-arg methods of a COM object with JACOB

When I try to call no-arg functions of a COM object with JACOM JVM crashes with the following error

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);
pEnv->ExceptionDescribe();

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]

JVM crash when adding method to class

Hello,
I am getting some kind of problem with the virtual machine. The JVM crashes when making a class (with new). It happened when I was adding some functionality to the class, I worked my way backwards and discovered it crashes when I add any new methods, if I comment them out again everything works, adding a method by any name causes to crash.
I went in debug to find out where it was happening, and it happens on this line:
public PerspectiveActionToolBarHeader createPerspectiveActionToolBarHeader() {
     PerspectiveActionToolBarHeader ret = null;
     ret = new PerspectiveActionToolBarHeader(this); // << here
     return ret;
}The PerspectiveActionToolBarHeader is the class where adding methods causes it to fail. For example, it has the method
public Container getContainer() {
     return this;
}and works, but if I add:
public void anything(){} it causes a crash on the new PerspectiveActionToolBarHeader(this);
When stepped into with the debugger it goes to the (source not found) ClassNotFoundException and eventually before the crash the (stack?) looks like this:
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available
MaldiSoftwareOptionsUIEnsemble(PerspectiveUIEnsemble).createPerspectiveActionToolBarHeader() line: 72
and the debugger describes the class just before the crash:
Launcher$AppClassLoader (id=44)
arg0     "saiman.uiobjnew.PerspectiveToolBarButton" (id=51) << has just changed
and the log file (not sure how much to copy here!):

I think I may have stumbled across the answer, It seems that the abstract class PerspectiveToolBar implements
the interface with the method public Container getContainer() but does not declare it, this should be fine because the method is abstract but it crashes. When I add the method public abstract Container getContainer(); to the abstract sub-class there is no error. I'm going to try make a small compilable example to see if I can reproduce it.
edit its actually only one of the two interface methods, and not getContainer(), but another one. If anyone is interested here is the interface:
public interface IMassSpectrometerPassableControlContainer
     Container getContainer();
     void reloadWidgetsOnVisible(boolean visible);
}and it works only if there is "public abstract void reloadWidgetsOnVisible(boolean visible);" in the abstract class PerspectiveToolBar implementing IMassSpectrometerPassableControlContainer.
I tried to reproduce it, but I can't get another class to repeat the behaviour, so I don't think I can post a bug report on it. Here is my attempt anyway:
import javax.swing.JToolBar;
* Class     Test.java
* Date:     7 Jun 2011
* @author     tofuser
public class Test extends Subclass
     public static void main(String args[])
          System.out.println("in main method");
          Test t = new Test();
          t.interfaceMethod();
     @Override
     public void interfaceMethod()
          System.out.println("interface method");
abstract class Subclass extends JToolBar implements Interface
     private static final long serialVersionUID = 1L;
     //this line is where it breaks in my code, including it works
     //public abstract void interfaceMethod();
interface Interface
     public abstract void interfaceMethod();

VB6 applications crashes when calling C# dll's in production environment

Hi All,
I'm basically .NET developer, not much aware of VB language or VB visual Basic 6.0.
We are trying to work out with VB application running/ using C# dll's. The scenario is like VB exe applications using C# dll's and C# dll's are referenced to VB application using .tlb file.
In development environment(debug mode) the application looks fine and working as expected. But when the same code is put into production environment VB applications are crashing when pointing to C# method calls. We trying to know the reason but application
is getting killed. The issue seems to be sporadic and not able to catch in MsgView(debug tool).
In one more scenario, the VB application is loading C# form and getting data back to VB but when we repeat the same workflow again application is crashing either in 2nd attempt or 3rd attempt.
Has anybody seen such issue? Any input is welcomed.
Thanks,
Shesh

Crash when calling Clipboard.GetContent() in Page Loaded event

Hello
I found a crash when using
Clipboard.GetContent() method ,
the steps to reproduce this are very simple:
-create C# Windows store application ,
-add loaded event for main page
-call Clipboard.GetContent() inside it(loaded event handler).
-run the application as release Ctrl+F5 , the application will crash , note that when you run as debug no problems
-this problem appears not on GetContent() only , it appears when you use any method of ClipBoard class indside main page loaded event.
Is this bug? , if yes , what is the workaround for this.

Hi shaker,
Firstly, I have to say that, yes, I can reproduce your issue on my side.
However, as far as I know that the Clipboard operations are used to enable users to cut, copy, and paste data, but why you just call the Clipboard.GetContent() method in the Grid_Loaded event? Could you please show me more information
about your requirement so that I can better understand your scenario?
Thanks.

Thanks again for your suggestion about Photoshop crashing since
trying to print with Yosemite. I did go to the Adobe site, then the Apple Apps,
and downloaded the new driver for the Epson Workforce 40 printer. Computer
restarted. Unfortunately, Photoshop still crashes. But I appreciate your idea, and
seems it should have worked. Happy Holidays!

When i open safari an apple alert comes up with a phone number. when i call i get put on hold forever. how do i get this off there?

when i open safari an apple alert comes up with a phone number to call. when i call i get put on hold forever or no one calls me back. how do i get this off there and what is it?

It's a scam. Do not call the number. There are several ways to recover.
1. Some of those scam pages can be dismissed very easily. Press the key combination command-W to close the tab or window. A huge box will pop up. Press the return key and both the box and the page will close. If that doesn't happen, continue.
2. Press and hold command-W. You may hear repeating alert sounds. While holding the keys, click the OK button in the popup. A different popup may appear, which you can cancel out of as usual.
3. From the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and uncheck the box marked Enable JavaScript. Leave the preferences dialog open.
Close the malicious window or tab.
Re-enable JavaScript and close the preferences dialog.
4. If the Preferences menu item is grayed out, quit Safari. Force quit if necessary. Relaunch it by holding down the shift key and clicking its icon in the Dock. None of the windows and tabs will reopen.
After closing the malicious page, from the menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
to get rid of any cookies or other data left by the server. Open your Downloads folder and delete anything you don't recognize.

Any help would be gratefully appreciated.

Are you running any A-V? If it's an iMac 21.5, I don't think you're running Leopard, 10.5. Probably at least Snow Leopard, 10.6. This is the Leopard forum.

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.<br />
You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

I've got a 15" white macbook which I bought about 2 years ago. It froze the other day and wouldn't respond so I shut it down. When I turn it on now it comes up with a flashing file with a question mark on it. How can I fix it?

I've got a 15" white macbook which I bought about 2 years ago. It froze the other day and wouldn't respond so I shut it down. When I turn it on now it comes up with a flashing file with a question mark on it. How can I fix it? I've tried a few things i've seen online but the futhest ive got is to put the start up disk in when you makes it go to a grey screen with an apple logo and the spinning wheel which then stops spinning. Can anybody help?

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on your keyboard once.It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left handlist. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.
