No, Maven will (correctly) close URLClassLoaders on java7 and will
continue to work as before on older JVMs. Here is the code that
implements this logic

Does this mean Maven will now require Java 7 as the running JVM?
Oddly - I don't see any close() method mentioned on:
http://docs.oracle.com/javase/7/docs/api/java/lang/ClassLoader.html
anywhere?

Yep, TrueZip will leave a JVM shutdown hook registered unless you
explicitly unmount the virtual file system after you're done with it - in
most cases this is just an oversight and unmounting will also help conserve
resources, see example in

nope there is a check here
https://github.com/sonatype/plexus-classworlds/blob/master/src/main/java/org/codehaus/plexus/classworlds/realm/ClassRealm.java#L63

Just as an aside, this sent me scrambling to my Javadocs; I see no such
close() method on ClassLoader in any version of Java? (See for example
http://download.java.net/jdk8/docs/api/java/lang/ClassLoader.html)
Typo?

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 )
