The Java autoconfiguration stuff dates back to before there was any free JVM other than Kaffe/japhar.

Virtually *all* of the logic in acjdk.m4 is obsolete and no longer useful. The threads stuff was just to enumerate the shared libraries that java would need so that it wouldn't be necessary for one wrapper script (javaswarm) to call another (kaffe), spawning lots of shells and being slow.

Specifically, there is no reference to threads at all in Swarm.

Choices are to 1) hack the acjdk.m4 along the lines of the code now for new versions, or 2) decide to strip down the number of AC_SUBST substitutions used in the Swarm Java makefiles and scripts. Maybe look around at new autoconf macro packages intended for Java and rework from there. 2 is clearly the better thing to do.

In retrospect, I think the javaswarm/javacswarm scripts were a mistake to introduce. Now people end up wanting to use Swarm in Eclipse or similar and end up having to bypass the scripts anyway. At the end of the day the idea is simple: provide a shared library and a .jar file, and other packages do that too.
