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

You shall use

ExitOnOutOfMemoryError or CrashOnOutOfMemoryError

and

HeapDumpOnOutOfMemoryError

OpenJDK JVM (Hotspot) at first takes the heap dump and then crashes out or exits as opted for.

To get a clearer understanding you may refer to JVM source file taking care of this particular logic.
