Suppose there is a large Java application and I would like to gracefully shut it down if OutOfMemory error occurs. Now I see the following problems:

  • Some components catch and “swallow” all Throwables including OutOfMemory
  • If a thread does not catch OutOfMemory it exits and we do not know that OutOfMemory occurred

Can I somehow register a “JVM-level” handler to catch any OutOfMemory, which may occur in the JVM?

    Some components catch and “swallow” all Throwables including OutOfMemory

    They shouldn’t do that, I would fix them.

    If a thread does not catch OutOfMemory it exits and we do not know that OutOfMemory occurred

    That I would fix as well.

    You can register an UncaughtExceptionHandler.

    The only option might be to trigger a script on an OOME which shuts down you program. This can be done from the command line.
