On what grounds do you not think that? PL/J uses an external JVM,
PL/Java one that is running in the backend process. (Or maybe it was
the other way 'round, I'm too tired to remember tonight.) That's a
really fundamental difference that makes them suited for very different
applications; not to mention the resulting different licensing scenarios.
The points that have been made in this thread about PL/J not being
actively maintained are important, but other than that objection,
I can see no reason that PL/J wouldn't have an equal claim to inclusion
in core. Perhaps more, because it gives us an extra layer of insulation
from JVM licensing questions.
