Bug 1357823

Currently in the HotRod client the SSLContext is created with the hardcoded "TLS" protocol. This prevents java 7 clients to make usage of TLS 1.2, since it is not enabled by default and needs "TLSv1.2" protocol setting to force it.


The client is running Java7 (JDG6.6) and the server is JDG7.
From the server log the connection fail with different messages, the reported version differ any time:
