The reason this has been flagged as a Beta blocker is that in conjunction with
JBEAP-9867, we can't configure encrypt protocols. This also blocks an RFE - EAP7-561.
When we tried to configure UDP stack in JGroups subsystem, we added ASYM_ENCRYPT protocol. According to the model definition attributes "key-store" and "key-alias" together with "credential-reference" child element had to be defined as well. Due to this configuration server failed to start with errors:
We should still be able to define original protocol behaviour without Elytron, but it seems we can not use encrypt-protocol without keystore definition in Elytron which could be a backward compatibility issue.
Used configuration in standalone-ha.xml is attached.
