Description Jaroslav Tulach 2009-02-04 17:33:15 UTC 
PS: There is 10s regression in start time described in issue 157829.

Oleg noticed that ModuleInstall for org.netbeans.modules.editor.completion/1 takes
dT=0.02s on average for 20081229 vs 4-6s for 200902

As the whitelist also indicates significant increase in # of loaded editor classes, it seems that some recent changes 
in editor are reason for the slowdown.

Comment 2 Vitezslav Stejskal 2009-02-05 07:24:37 UTC 
Most likely a regression caused by fixing issue #156127. The fix was probably too aggressive in initializing editor
keybindings. I'm looking into it.
