Don't take these tests too seriously.  They are old and using package 
layout patterns (what files are where) to identify the JDK on different 
platforms.   For example, there's nothing in Swarm that cares about the 
threads model.    The relevant m4 macros really should be stripped 
down.   There are probably new JDK-related macros that can do the same 
job in a more concise way.  Someone should fix this autoconf stuff in 
Swarm because it is broken.

Most of the cruft in the M4 code for Java in Swarm is only for the sake 
of extracting `javaswarm' script that would work with various (again 
old) java implementations.   Minimally, to use Swarm with Java, you just 
need to be able to compile the libjavaswarm in java/c and the java/swarm 
class files and the jar file.  If you can get that to build, with 
whatever hackage, then you have everything that matters.  To use it the 
task is just to set the LD_LIBRARY_PATH as needed (to Swarm's 
libjavaswarm.la install location) and its .jar files.    The script does 
that (and deals with historical java implementation issues), but you can 
do it manually just as well.
