org.netbeans.modules.glassfish.javaee.Hk2JavaEEPlatformFactory.getJ2eePlatformImpl is spending about two minutes in ZipFile.open() and because it is called under project read lock it blocks other code.
See http://hg.netbeans.org/web-main/rev/c0748a32373c this probably resolved the issue... since the initLibraries will return immediately.
