stacktrace
Another issue with Class loading. The message: [ModuleCL@6c98a8b8[org.netbeans.modules.xml.jaxb]] and declared parents [] seems strange, because the the xml.jaxb module has a lot of dependencies. I cannot reproduce according to those instructions. Are you omitting some steps? About the message - the declared parents are those of MainImpl.BootClassLoader, for which [] is correct. The issue is that when LazyLookupProviders.loadPSPInstance is called, Thread.currentThread.contextClassLoader is still MI.BCL, rather than ModuleManager.SystemClassLoader. This would be true during early startup, before the module system is really initialized. Why the above code is running at that time, I don't know. I can try to change RequestProcessor to effectively set SLOW to true when running with assertions on, since we generally want to capture origin stack traces in development builds. Integrated into 'main-golden', will be available in build *200904281401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/3b30abd0e2b6 User: Jesse Glick <jglick@netbeans.org> Log: Turning on "slow" mode (i.e. show who posted an RP task that ended in failure) whenever asserts are on. Also improve display of result to be a single log record, better for exception reporter. See #163676 for an example bug report which could more easily be diagnosed with such information. *** Issue 164378 has been marked as a duplicate of this issue. *** Nothing new for a couple of months. |
