At this point in time, a much more important feature of PostgreSQL
would be for version 8.3 to be released.  That process is running into
*some* problems vis-a-vis the review process.

The last that I heard, it was somewhat indeterminate whether pljava or
pl/j (a separate project) was the preferred way to provide Java
support.

The fact that Oracle or IBM are marketing their Java support heavily
*does not* imply that it is a good idea for the PostgreSQL project
ought to do the same.  We have limited time; taking time from other
things to spend on pljava is quite likely not to be a wonderful idea.
It requires that people whose expertise *isn't* Java spend a lot of
time learning Java details.

If there aren't enough people interested in supporting Java, then it
is by no means evident that anything can or should be done.
