A grab bag of problems lumped together by slowness reporter. Assigning arbitrarily to the first class I see (acc. to reverse chronological order); feel free to file bugs for other components, or just reassign when fixing your part, etc.

#349605, #339615, #331018: WebActionProvider.getTargetNames calls GlobalPathRegistry.getSourceRoots, which can be time-consuming when a lot of projects are open. ("we find all projects containg a web service" - is this really necessary? can it be precomputed, or done asynch with a progress notification?)

#345084, #338820,  #338735, maybe #338801: FormEditor.saveFormData results in JavaCodeGenerator.regenerateCode being called, which can apparently be quite slow, and is a bit surprising. #338797, #338797 related.

#344989: Maven's JumpAction runs in EQ even though it does some relatively expensive classpath calculations.

#333845: parsing.impl.indexing.RepositoryUpdater reacting to file change events synchronously, could probably do this asynch instead.

...and then I got tired of categorizing them.

WebActionProvider.getTargetNames() performance problems are already tracked as issue 182840. Passing to form.

A pile of trash created by slowness reporter => closing as invalid.
