Java binding fixes.
* subversion/bindings/javahl/src/org/apache/subversion/javahl/NativeException.java,
subversion/bindings/javahl/src/org/tigris/subversion/javahl/NativeException.java

NullPointerException if message is null.

(testGetMessage): New function to test getMessage's handling of a null message.
