When running Java2Demo with 2D PIT, it threw java.lang.NullPointerException
pit build: /net/jcg-x86-01/export3/Java2DBuilds/2004-03-03.tiger.pit
platforms: Mercury, QuickSilver b06

Regressed with Beta2 b41, 40, 39, 38, 33, b32 all reproducible.
Harder to reproduce on b31, b30.

To reproduce: launch Java2Demo, then click on few tabs, then the exception happens.
