See Which Cipher Suites to enable for SSL Socket? and use SSLSocketFactoryEx. Its a drop-in replacement for Java's SSLSocketFactory

If you don't want to use SSLSocketFactoryEx, then rip the code to find the intersection of cipher suites.

It controls both protocols and cipher suites. There are no unexpected surprises, like getting a SSLv3 socket back from SSLSocketFactory.getInstance("TLS");.

Nothing is configurable, so the user cannot shoot themselves in the foot. It's also ready for TLS 1.3
