Description Hirotaka Matsumoto CLA 2005-02-03 06:06:16 EST 
java indexing sometimes throws npe when lots of plugins ( around 300 )
are in the workspace so that some functions, i.e. Open Type,
don't work at all.

Which VM are you using?

Is it IBM build cxia321411-20040301? If so, there are newer versions of this 
VM available - you should switch.

Suspect this is a duplicate of bug 66836
