Looking at http://statistics.netbeans.org/exceptions/exception.do?id=699664

30s in org.netbeans.ModuleManager$SystemClassLoader.loadClass()	is blocked by at least 24s in "ErrorAnnotation worker" waiting to load a META-INF/services resource. There is also "main-class-updater" loading something from ZIP files, but probably unrelated.

Not sure what to do about this.
