-------------------------------------------------------------------

Apparently the problem is lacking support for DHE keys < 1024 bits. In Sun jdk this was fixed in 2013 while openjdk is still not corrected. 
In http://stackoverflow.com/questions/6851461/java-why-does-ssl-handshake-give-could-not-generate-dh-keypair-exception the solution they found was to remove the *DHE* cypher and force using a different cypher.
