Question

My application is crashing from time to time. Looking at windows crash dump, the following seems interesting: 

ExceptionAddress: 000000006abc0608 (jvm!JVM_ResolveClass+0x000000000001d6b8)  
   ExceptionCode: c0000005 (Access violation)  
DEFAULT_BUCKET_ID:  NULL_CLASS_PTR_READ  
ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.  
FAILURE_BUCKET_ID:  NULL_CLASS_PTR_READ_c0000005_jvm.dll!JVM_ResolveClass  
BUCKET_ID:  X64_APPLICATION_FAULT_NULL_CLASS_PTR_READ_jvm!JVM_ResolveClass+1d6b8

Can you please assist with how should I analyze it? How can I tell if it's something in my application code or in the JVM code?

Thanks

Solution

Your Java program should not be able to crash the JVM (I assume you're not using JNI or similar).

I would upgrade your JVM and try a newer version.

OTHER TIPS

Seems to be a JVM issue. I would recommend trying your application on another computer just to be sure. Make sure you're using the latest version of Java as well.
