I thought of this...the obvious way would be to subclass
AbstractExecutorService and override the Executor.execute method by
delegating to the wrapped custom Executor instance. But for this to
work, all relevant methods in AbstractExecutorService (the submit and
invokeXXX methods in particular) should ultimately call
AbstractExecutorService's own published execute method, which is not
necessarily the case. It is possible that the submit and invokeXXX
methods of AbstractExecutorService directly call the execute method of
a contained (default) Executor instance -- and I found nothing in the
API doc which would encourage me to think the contrary.
