These happen from time to time. Seems to be some sort of synchronization bug
in the VM classloader.
Only real cure is to try/catch(LinkageError) fairly early and simply retry. It
always seems to work the second time.
Around org.apache.tomee.catalina.LazyStopWebappClassLoader.loadClass would be
good.
Do a search for usages of LinkageError in the codebase and you'll see a handful
of other places we've had to apply the same band-aid.
