Funny, I'd recommend catching Throwable. I've been caught out (no pun
intended)
by just catching exceptions, the Throwable (dreadful name by the way) I was
getting prevented the application working but wasn't reported anywhere.
Put it this way. Do you want to ignore OutOfMemoryErrors? Your app. can't
possibly
work correctly if you ignore these.
