Description Alexander Kouznetsov 2008-07-16 19:06:34 UTC 
Performance whitelist test reports that the following classes are being loaded on NetBeans startup:

org.netbeans.modules.jumpto.symbol.GoToPanel$ContentProvider
org.netbeans.modules.jumpto.symbol.GoToSymbolAction
org.netbeans.spi.jumpto.symbol.SymbolProvider

This is considered as NetBeans performance regression. Please remove these classes from NetBeans startup.

This issue is based on jtulach's comment:
Report a bug for the module to switch to new declarative actions 
(Actions.alwaysEnabled or TopComponent.openAction)

Comment 2 Jan Lahoda 2008-08-19 12:54:50 UTC 
TopComponent.openAction is not appropriate for this action (GoToSymbolAction).

The GoToSymbolAction is enabled if at least one project is opened (and this was a requirement for the Go to Type action,
which is the parent of the Go to Symbol action). So Actions.alwaysEnabled.

The most appropriate way, IMO, to fix this is to provide an action wrapper similar to Actions.alwaysEnabled, which would
keep the action enabled iff at least one project is opened. Please provide such a wrapper.
Comment 3 Jan Becicka 2008-09-25 10:32:43 UTC 
Please provide action and reassign back
Comment 4 Alexander Kouznetsov 2008-09-30 15:50:55 UTC 
Two classes were added to whitelist according to comment in issue 147847:

org.netbeans.modules.jumpto.symbol.GoToPanel$ContentProvider
org.netbeans.modules.jumpto.symbol.GoToSymbolAction 

See http://hg.netbeans.org/main/rev/26975c90e0ca 

Third class is not loaded any more.
