Eugene Kuleshov: debugging JVM crashes or more on -XX options
Roman Kennke discovereda very useful -XX JVM option for debugging JNI code:

java -XX:OnError="gdb - %p" MyApplication 

This fires up gdb whenever an error occurs, and sets up all the libraries etc for debugging. Very nice. Ideally you do this using a debug build of OpenJDK, so get get as much useful information as possible.

While back, I've created " The most complete list of -XX options for Java 6 JVM", which has the following description for OnErrorflag:

Run user-defined commands on fatal error; see VMError.cppfor examples

As advertised, VMError.cppdoes show few more neat examples:

// -XX:OnError=, where  can be a list of commands, separated
// by ';'. "%p" is replaced by current process id (pid); "%%" is replaced by
// a single "%". Some examples:
//
// -XX:OnError="pmap %p"                // show memory map
// -XX:OnError="gcore %p; dbx - %p"     // dump core and launch debugger
// -XX:OnError="cat hs_err_pid%p.log | mail my_email (at) sun.com"
// -XX:OnError="kill -9 %p"             // ?#!@# 

On Windows there is also -XX:UseOSErrorReporting option, which would use system error reporting, such as Dr.Watsonor a debugger registered instead.

It would be really neat to somehow use those options to hook up Eclipse CDTdebugger to the failed process.
