> SaslRpcServer.SASL_PROPS is a SASL server property and should stay constant after initialization.
In the initial implementation, we assumed all SASL clients will use the same constant value.
If different clients might use different values depending on the conf in the getProxy() call
(as current code implies), each client should have its own copy. In any case, a client shouldn't
re-initialize server's copy.
