javax.net.ssl.SSLHandshakeException: Server chose unsupported or disabled protocol: SSLv3

If you get this error message "javax.net.ssl.SSLHandshakeException: Server chose unsupported or disabled protocol: SSLv3",
chances are that your JVM, for vulnerability issues connected to SSLv3, is configured to disable this protocol.
If you REALLY need to support SSLv3, check which file you are using for -Djava.security.properties=/path/to/yourfile, then edit yourfile and make sure your property:
jdk.tls.disabledAlgorithms=SSLv3, DH keySize < 768
doesn't contain SSLv3 (make it jdk.tls.disabledAlgorithms=DH keySize < 768)
