Re: Program works in Local but not in Distributed mode

[Steven van Beelen <sm...@gmail.com>]

I solved the problem my self. It was due too the fact my own Writables had
some serialization problems (Null pointers when reading back to an object
which I instantiated incorrectly).
The reason I point this out, is that it did not stop the program from
running.
Shouldn't such an error stop the program entirely? Since no messages could
be received because of it, the program has no need to run any further.
