Jardo, help please! :-)

Comment 3 Vitezslav Stejskal 2008-04-09 10:09:11 UTC

Martine, were there any other exceptions in the log file? It looks like the document was not loaded for some reason...

Comment 4 Martin Schovanek 2008-04-09 10:19:38 UTC

Any other visible exception, but the document is use to throw another NPE, see issue # 132374.

Comment 5 Jaroslav Tulach 2008-04-09 10:34:42 UTC

I've seen it yesterday as well and it was not related to web or jsp. I think I was working with plain java se project 
and java sources.

Comment 6 Jaroslav Tulach 2008-04-09 14:51:21 UTC

The NPE can happen only if Timers/Counters module is enabled. There is "if (TIMER.isLoggable(Level.FINE))" check 
around line 261. Timers/Counters module is never part of release, that is why I do not think this needs to be fixed 
for 6.1.

> Timers/Counters module is never part of release
It wasn't for NB 6.0.1 , but I see it in NB 6.1 RC1 - Tonda, is it intentional ? I mean the whole memory toolbar is
disabled by default, but plugin is part of the build and memory toolbar can be enabled as well.
