Vito, please take a look at it. Thanks. It's still the same story, which I'm pretty sure Jarda already knows. In short: pre-project formatting settings -> need ProjectManager.mutex() -> when opening projects somebody else holds the mutex -> we can't open a document, render it or do pretty much anything else and end up blocking AWT. The real question is 'do we need to writeLock the mutex'? Maybe not, see issue #142767. Is anybody bold enough to make the change suggested in #142767. I guess not, so it's probably gonna have to be me. (puke) With #142767 fixed I also changed CodeStylePreferences to use readAccess, which should improve the situation. http://hg.netbeans.org/main/rev/917a3b0e6eb2 Integrated into 'main-golden', will be available in build *200809051401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main/rev/917a3b0e6eb2 User: Vita Stejskal <vstejskal@netbeans.org> Log: #146155: AuxiliaryConfigBasedPreferences.node now uses readAccess (see #142767) and we can now use readAccess too |
