[java] mvn branch

[Steve Vinoski]

Under branches/mvn is a first cut at building and testing the java  
code with maven. I would appreciate it if others could checkout the  
branch and try it, especially on platforms other than OS X. All  
feedback welcomed.

BTW, be sure to get "mvn" and not "maven" as the latter is an old  
branch that doesn't work and needs to go away.
