Description

Run into the following while doing some troubleshooting:

------
If you run your application with the VM flag -XX:+HeapDumpOnOutOfMemoryError a heap dump is written on the first Out Of Memory Error. There is no overhead involved unless a OOM actually occurs. This flag is a must for production systems as it is often the only way to further analyze the problem.
------

IMO, it would be good if we get all startup scripts add this option to the java calls.
