Unregisters the supplied transformer. Future class definitions will not be shown to the transformer. Removes the most-recently-added matching instance of the transformer. Due to the multi-threaded nature of class loading, it is possible for a transformer to receive calls after it has been removed. Transformers should be written defensively to expect this situation.

Parameters:

transformer

the transformer to unregister

Returns:  true if the transformer was found and removed, false if the transformer was not found

Exceptions:

java.lang.NullPointerException

if passed a null transformer
