I made a very small test, I chaged my path to jre/bin/server in place of jre/bin/client,  and executed SELECT sqlj.get_classpath('public')... it worked. 
 
I would like comments about the implications: what about performa ? and compatibility ?
 
Regards.

PL/Java supports both the client and server JVM. The best choice depends 
on your use-case. The server will typically outperform the client during 
long and heavy sessions at the cost of higher memory consumption and 
some degraded performance initially. Since a PostgreSQL backend is 
single-threaded and each session spawns a JVM of it's own, the higher 
memory consumption imposed by the server may not be worth it.
