JPL is languishing, no longer in vogue apparently. Although
part of the Perl distro, it requires a core patch in order 
to work.  The patch was made to the core but then went MIA
circa 5.8 as I recall. A colleague in my area did update the 
patch to work with an early version of Perl 5.8.x. However, 
it hasn't been submitted to p5p. Also, I've been hoping/
fantasizing about working on a nicer install too (with a 
configure, Makefile.PL, etc.) instead of the existing 
makeshift shell script.

I don't know enough about that to comment.

I've only played with Inline::Java a little but it works well.
That's limited to the other direction though as I recall: embedding 
Java in Perl. However, if you have a large legacy Java app, in need
of some embedded Perl to maintain your sanity, you'll need JPL. My 
colleague reports JPL has worked wonderfully to provide some Perl 
amenities within a huge Java app. Hopefully, JPL won't be circling 
the drain for quite a while yet.
