Description _ rkubacki 2004-10-05 16:58:36 UTC 
During IDE start JavaEditorComponent creates Timer
for each Java editor and schedules its execution
after short delay. This causes initialization of
editor pane including creating of toolbar for all
Java editors. We should schedule this timer only
for active component as the code triggered by this
is only improtant if the TC is active (creates/set
active nodes)

The dumps from NavigationView are attached. The combo box is created
and addNotify is also called on them.

Comment 5 _ rkubacki 2004-10-20 15:49:57 UTC 
This timer also triggers update of fold hierachy that in turn request
resource parsing. Pretty bad.
