Question

I suspect in my application that an outofmemoryerror is causing a a run() to exit, however because there were no logs, the error wasn’t visible.

What should i do in this case?

Answer 1

I don’t know about others, but never (IMHO) catch or throws anything that extends Error. The followig statement from the javadoc states:

A method is not required to declare in its throws clause any
subclasses of Error that might be thrown during the execution of the
method but not caught, since these errors are abnormal conditions that
should never occur.

An Error is printed with System.err and if you want to avoid OutofMemoryException, increase your heapsace instead.
