Java heap dump & shut down - what order?

Question

I would like to detect an OutOfMemoryError, take a heap dump, and automatically exit the Java program. Say I have the following command-line arguments for my JVM:

Answer 1

I would rather rely on calling into a script that handles the ordering more deterministically i.e.

-XX:OnOutOfMemoryError="//heapAndQuit.sh"

heapAndQuit.sh will then employ a method to find the pid of the current process. One simple way to identify the pid is to use the log file location your process is writing to

lsof | grep /var/tmp/ | cut -d " " -f1 | uniq

I will then use jmap to dump and kill -9 subsequently
