Dear friends, why won't this code resizing a GIF image work on Linux with JDK 1.5? It works well on WinXP with JDK 1.6. On Linux it just produces an empty thumbnail image.

This shows you why should never ignore any exception unless you are 100% sure it will not occur. In that case, you should document WHY it will not occur; not only for other programmers to read, but also for yourself months later.

In any case where the exception might (or will) occur, at least print its stack trace.

At work, we even don't ignore those exceptions. We "document" them by throwing an UnreachableCodeReachedException (which is a runtime exception), and sign it with our initials:

At the risk of being transferred to Meaningless Drivel, throw new TheChequesInThePostException();

catch(AvoidingTheQuestionException){
Actually, Linux with JDk 1.5 doesn't seem to support GIF writing in the standard libraries. I must upgrade to 1.6 or use third party library.
