Comment 5 dlipin 2008-11-26 12:55:42 UTC 
I see that PluginManager class is not accessible from the pluginimporter`s StatusLineImportIcon class, 
NoClassDefFoundError is thrown. I am not sure whether the initial assertion error is caused by this issue..

Jirka, any idea? are those issues related at all? are they connected to Issue 152964?

Looks like this issue happened in the past when no pluginimporter existed..

Comment 6 Jiri Rechtacek 2008-11-26 13:01:10 UTC 
Seems as a race condition, need to find out reproducible use case and debug it. It has nothing to do with
pluginimporter, this problem was reported in the past also.
Comment 7 dlipin 2008-12-26 16:48:41 UTC 
Just to note: this "Updates Flasher cannot be null" assertion failure sounds very similar (at least, after the code 
analysis) to the NPE that is mentioned in the Issue 137816.

Comment 10 dlipin 2009-03-25 14:27:49 UTC 
That is likely fixed with the new Notification API used (see Issue 159614 and http://hg.netbeans.org/main-silver/
rev/568f7ed5bbba).
