Examples of ptolemy.kernel.util.InternalErrorException

ptolemy.kernel.util.InternalErrorException
This exception should be thrown if an unexpected error is encountered other than one for which InvalidStateException would be appropriate. Our design should make it impossible for this exception to ever occur, so occurrence is a bug. This exception is a RuntimeException so that it does not have to be declared. @author Edward A.
