Ethan Atkins 8fd10bfb5f Make all test and run classloaders parallel capable 
A number of users were reporting issues with deadlocking when using
1.3.2: https://github.com/sbt/sbt/issues/5116. This seems to be because
most of the sbt created classloaders were not actually parallel capable.
In order for a classloader to be registered as a parallel capable, ALL
of the parent classes except for object in the class hierarchy must be
registered as a parallel capable:
https://docs.oracle.com/javase/8/docs/api/java/lang/ClassLoader.html#registerAsParallelCapable--.
If a classloader is not registered as parallel capable, then a global
lock will be used internally for classloading and this can lead to deadlock.

It is impossible to register a scala 2 classloader as parallel capable
so I ported all of the classloaders to java.

This commit updates the java-serialization scripted test. Prior to the
port, the new version of the test would more or less always deadlock.
After this change, I haven't been able to reproduce a deadlock.

This had no significant performance impact when I reran
