when I start my Java-Program, I get this error (using Xuggle-library with Webcam):

Problem signature:
Problem Event Name: APPCRASH
Application Name: java.exe
Application Version: 6.0.260.3
Application Timestamp: 4dc11607
Fault Module Name: libxuggle-ferry-4.dll
Fault Module Version: 0.0.0.0
Fault Module Timestamp: 4b9493c5
Exception Code: c0000005
Exception Offset: 0000822a
OS Version: 6.1.7601.2.1.0.256.48
Locale ID: 1031
Additional Information 1: 0a9e
Additional Information 2: 0a9e372d3b4ad19135b953a78882e789
Additional Information 3: 0a9e
Additional Information 4: 0a9e372d3b4ad19135b953a78882e789

I have already found out, that c0000005 is an access violation. Is there a way to solve such errors? Or how can I trace this error (Stacktrace or something, or maybe some tools for this)? Does Java create logfiles for such errors. Where can I find them? My Java-Program does not throw any exception. I just get this appcrash and "Java Result: -xxxxxxx" (where xxxxxx is a large number).

Thank you.

Java didn't crash, your dll did, and it took the Java process down with it. You won't see an exception. Typically when the JVM is about to die it creates a file that lists what was going on at the time, and it writes a message to stdout with a path to this file. Here's the beginning of one I got not too long back:

A fatal error has been detected by the Java Runtime Environment:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x1002ff3a, pid=4312, tid=2120

JRE version: 6.0_24-b07 Java VM: Java HotSpot(TM) Client VM (19.1-b02 mixed mode, sharing windows-x86 ) Problematic frame: C [namechangedtoprotecttheguilty.dll+0x2ff3a]

If you would like to submit a bug report, please visit: http://java.sun.com/webapps/bugreport/crash.jsp The crash happened outside the Java Virtual Machine in native code. See problematic frame for where to report the bug.

--------------- T H R E A D ---------------

and it goes on to list what's in the registers, what the stack frames look like, what's on the heap, environment variable values, etc.

  • great answer, but I don't find anything in the stdout that gives me the path of the error log, can you kindly help me solving that ? http://stackoverflow.com/questions/27729672/java-crashes-when-calling-dll-function-using-jna – Muhammed Refaat Jan 01 '15 at 12:03

The developer of libxuggle-ferry-4.dll should fix the library.
