Description

RemoteException has a number of undocumented behaviors

• o.a.h.ipc.RemoteException has no javadocs on getClassName. Reading the source, the String returned is the classname of the wrapped remote exception.
• RemoteException(String, String) is equivalent to calling RemoteException(String, String, null)
• Constructors allow null for all arguments
• Some of the test code doesn't check for correct error codes to correspond with the wrapped exception type
• methods don't document when they might return null
