What happened here is that the JavaVM caught an exception while parsing
the code. It won't cause any problems AFAIK but it will keep a program
from working ;-).

Generally speaking you use try {} catch () {} to deal with raised
exceptions in Java so that if an error does happen it is delt with
properly or errors out in such a manor that the user can understand why.
