kohsuke 975f36e73a fixed a bug regarding a roundtrip exporting (where side X exports an object to the other side Y, and Y re-exports that back to X.) 
When this happens to classloaders (that is, when the master exports its classloader to a remote machine, which re-exports this remote classloader to the master to make a callback), we end up creating a RemoteClassLoader on the master to load a duplicate copy. A duplicate copy happens when we try to load a class from plugins, because ImportedClassLoaderTable creates new RemoteClassLoader with the 'getClass().getClassLoader()' as the parent, which doesn't see the plugin classes.
To fix this problem, RemoteClassLoader is modified to detect the situation where a round-trip re-exporting is about to happen. Upon detecting this, it will arrange things in such a way that the other side will get the original ClassLoader instance back, instead of doubly-proxied RemoteClassLoader.
This fixes the problem discussed in http://www.nabble.com/Help-Kohsuke%21-m2-project-type-and-cobertura-tf4829718.html and http://www.nabble.com/MavenReporter-throws-Serialization-Exception-for-ProjectActions-when-writing-to-build.xml-tf4784290.html#a13687067

 2007-02-22 01:42:11 +00:00
kohsuke 8aac70529d there was apparently some kind of race condition, because occasionally test fails trying to call close once too many (that is, one channel (X) sends CloseCommand to the other (Y), which sends back CloseCommand to X, and somehow X sends one more CloseCommand to Y, causing an exception below.) 
I thought the use of the 'close' field and synchronization is enough to guard against this condition, but apparently it's not. I added one more 'closing' field, which seems to fix the problem.
It just doesn't feel right when you fix the issue without getting to the bottom, but the concurrency bug is hard to reproduce and I'm exhausted.
