java.lang.ClassNotFoundException: org.netbeans.modules.xml.jaxb.model.JAXBWizProjectOpenedHookImpl starting from org.netbeans.MainImpl$BootClassLoader@2a0ecd7e with possible defining loaders [ModuleCL@6c98a8b8[org.netbeans.modules.xml.jaxb]] and declared parents 
Created attachment 80931 [details]
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
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)

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.
