John Vines commented on ACCUMULO-1411:
--------------------------------------

This isn't as simple as changing the getClassLoader() method to using the classloader used to load AccumuloClassLoader as the shell seems to break (all the tests fail).

> We have a situation where there is a test client which spins off a Thread running a MockAccumulo, and then we try to use iterators that are on the classpath for that Thread. Unfortunately, they CNFE. We've traced it back, since the ReloadingClassLoader just uses the parent classloader (AccumuloClassLoader) in absence of configurations. The AccumuloClassLoader.getClassLoader uses ClassLoader.getSystemClassLoader() as it's parent, not AccumuloClassLoader.class.getClassLoader(). I believe that should preserve the way the classloaders work in the standard use cases while not breaking in any other cases.
