As can be seen from the attached snapshot, code completion is waiting for the parser lock held by an extremely slow hints computation inside html editor. Reassigning.

Composite component libraries *first time initialization* involves many index queries. If there's more libraries this may take some time.

But the *biggest sore point is FaceletsLibrarySupport.checkLibraryDescriptorsUpToDate()* which is very slow but called very often. This problem I believe must be addressed!

Although this bug is assigned to JSF Editor, it appears in Java Editor.
It is reproducible within my sources when I invoke autocompletion after a new statement.
Since I'm using a very fast computer, it usually delays my work "only" 3-4 seconds. I guess it will be even longer on a medium fast computer.
