StepIntoActionProvider is waiting for the Java parser.
The parser seems to be busy by RepositoryUpdater, which is scanning files. Unfortunately during scanning of files the parser does not provide any data.

This can not be fixed in debugger.

Moving to Java for evaluation - IMHO this is an annoying characteristic of the parser - the parser data are inaccessible during update. I'd expect that as soon as the initial scan is done, the data should be always accessible.

As of NetBeans 7.2, scanning runs on background.
