I have a Java app that makes use of some native code, and it's faulting. I want to find out where it's faulting, but I'm not sure how to read the hs_err_pid dump file:
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)

Basically, what are the 'j' frames pointing to? Is V+158 referring to the
bytecode offset in the class? How can I trace back from this to the source
lines in play?
Actually, I'd love a general guide to grokking these dumps. That'd be fantastic, too.
For a general guide have a look at these two links Fatal Error Log Troubleshooting and Crash Course on JVM Crash Analysis
