The short answer: You don't. It's an incredibly bad idea.

The long answer: You catch Error - or OutOfMemoryError if you want that 
specific one. So, you could try and catch it and handle it, but most of the 
cleanup during the unwinding of the stack gets skipped. scope statements and 
destructors don't get called. Your program is not likely to be in state where 
it makes any real sense to try and continue. You _can_ do it, but it's a bad 
idea.
