it must be an jdk-related problem
i do see it on ibm 1.3
i do not see it on sun 1.3.1

Exactly, I was going to ask if you were using the IBM JRE ? Smells like another 
JIT issue.

Comment 3 Philipe Mulet

Works as long as using another JRE. The involved code cannot throw any NPE.

Please add steps to reproduce this problem.

i can get the jdk info - it should be easy to reproduce then
because you get that NPE pretty much anything you try in eclipse
