The first obvious problem is that WebSources uses RequestProcessor.getDefault() and not one dedicated processor. 
Please fix that.
Comment 3 David Konecny 2009-09-24 23:51:31 UTC 
re. "WebSources uses RequestProcessor.getDefault()" - Jardo, WebSource does not use RP at all. Default RP used in
snapshot is coming from org.netbeans.modules.project.ui.Hacks.RP but that one you fixed already as well (issue 170029).
Is there something else to be fixed or can this issue be just closed?
Comment 4 Jaroslav Tulach 2009-10-01 16:22:16 UTC 
New evaluation of the problem (I've learned how to read the snapshot): AWT is waiting for a ProjectManager's lock for 
6s. The lock is hold by 3rd thread "Default RP" inside WebProjectProperties.save(). The WebProject.Info.getName() 
method shall be made faster, non-blocking, I guess.

However this seems just a single report, without duplicates, so I am downgrading to P4.
