Is there anything like .NET's NotImplementedException in Java?
887
An UnsupportedOperationException is a runtime exception in Java that occurs when a requested operation is not supported. For example, if an unmodifiable List is attempted to be modified by adding or removing elements, an UnsupportedOperationException is thrown.
The NotImplementedException exception indicates that the method or property that you are attempting to invoke has no implementation and therefore provides no functionality. As a result, you should not handle this error in a try/catch block. Instead, you should remove the member invocation from your code.
Commons Lang has it. Or you could throw an UnsupportedOperationException.

I think the java.lang.UnsupportedOperationException is what you are looking for.
