Xpress Version 2 + will not talk to older versions of Xpress

Allow XpressDispatch Version 2 + to talk to older versions of XpressStation. Error is
dhpublickey does not comply to algorithm constraints

This occurs because Java JRE 8 will not allow cyphers less than 1024 bytes, so the XPress handshake fails.

To workaround do the following:

Edit the following file:


Comment out the following line:
"jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \"
and then add
"jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768, \"
