I was trying to run fresh install of NetBeans 3.5
on IBM's JDK version 1.4.1:
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.4.1)
Classic VM (build 1.4.1, J2RE 1.4.1 IBM build
cxia32141-20030522 (JIT enabled: jitc)).

Slash screen displayed and it goes to "Opening
project Default" but then following exception is
thrown:
Annotation: Exception occurred in Request Processor
