java.util.EmptyStackException on JIT/Warmup

I'm using a 3rd party lib in my application that throws a java.util.EmptyStackException

This only happens during the VM JIT/Warmup

• Start application
• Start stress test no rampup.
• java.util.EmptyStackException thrown
• Keep application and redo stress test. No exception thrown

• Shutdown application

• Start application

• Start stress test with rampup. No exception thrown

I could keep reproducing this over and over.

Anyone have any ideas on how I can trace this so I can give more info to the vendor? Or why it could even be h开发者_运维技巧appening?

Thanks

It sounds like a bug in the vendor lib. Send them the full stack trace. Try to write the smallest possible program that can produce this exception in their code and send that to them too.
