Your query involved an intersection() that couldnt be computed.  PostGIS 
is giving you more information, but Java isnt reporting it.  Try 
executing the same query directly to postgresql (using psql) and you 
should see what the error message is.

Very small examples to reproduce the error are always helpful!
