"It seems that the org.eclipse.wst.jsdt.debug.ui is adding the ExternalSourceProjectFilter to the package explorer view, I'm not sure why it needs to be loaded for Java files."

There does not appear to be an option on either to say "don't start my bundle if it is not already started", so I am not sure we can do anything (unless we remove the filters).
Do we need the filter on the Package Explorer? Alternately can we move our filter class into a separate package and exclude it from the lazy Bundle-ActivationPolicy?

This looks fine to me as the filter is not doing anything fancy that would require a BundleContext at this point.
(In reply to comment #4) > This looks fine to me as the filter is not doing anything fancy that would > require a BundleContext at this point. +1 for the change the activation policy. -1 for adding the filter class as new API. The manifest should be updated to set the x-internal flag on the new package.
also noticed we don't correctly set the x-internal flag on 1. *.internal.ui.breakpoints.* 2. *.internal.ui.display 3. *.internal.ui.source.* opened bug 320902 for that issue.
Created attachment 175220 [details] updated patch Updating the patch. We actually were not exporting that package, nor several others, so the patch changes that and appends the internal attribute for them. It also doesn't remove the key from the previous Messages class since I'm hoping Babel will pick up on the two values being identical as a result and reuse the existing translations.
+1 looks good to me. Applied patch to HEAD, thanks Nitin.
