> The drawbacks to continuing running (generating internal errors in strange places) outweigh the benefits (maybe having the thread that OOM'd freed will allow us to serve some other requests successfully).
> I'm guessing that adding if (e instanceof OOME) { system.exit() } in our DefaultUncaughtExceptionHandler would do the trick.
> Only question is, would that happen before or after the XX:+HeapDumpOnOutOfMemoryError gets to fire?
