----------------------------------
Summary: Investigate how plugin classloaders are shutdown
Key: MNG-5589
URL: https://jira.codehaus.org/browse/MNG-5589
Project: Maven 2 & 3
Issue Type: Improvement
Affects Versions: 3.2.1
Reporter: Jason van Zyl

Stuart's analysis of the above thread:
I suspect this is related to the change in Classworlds 2.4.1+ to use the
new ClassLoader.close() method available in Java7 to forcibly close plugin
ClassLoaders when the plugin/container realm is disposed. This happens
after the Maven build is finished, but before JVM shutdown hooks run.
Any plugin that registers a JVM shutdown hook which tries to load
classes/resources from the original plugin realm will throw a NCDFE -
you'll probably see similar issues if a plugin forks threads that are still
running after the plugin/container realm has been disposed and subsequently
try to load classes.
( note that the same error will likely occur with Maven 3.1.1 since it uses
the same version of Classworlds )
