When running a build on a remote node, the RemoteClassLoader on the node will retrieve classes over the
network from the Hudson master and persist them locally.

The problem is that a class's package structure is not created in the filesystem, so a class with the
resource name "x/y/Z.class" will be persisted as "Z.class". This creates problems for example with code
that uses one of its own classes to find where it is located on the local disk, like Ant initialization.
