[Bug 1314116] [NEW] SSL returned when requesting TLS Context
Public bug reported:
OpenJDK-7 provides a SSL context when requesting a TLS context.
According to the JavaDocs, 'SSLContext.getInstance("TLS")' should
return a TLS context, and I should *not* receive a context capable of
SSL
(http://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLContext.html#getInstance%28java.lang.String%29):
Returns a SSLContext object that implements the specified secure
socket protocol.
And the docs on 'getEnabledProtocols'
(http://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLSocket.html#getEnabledProtocols%28%29):
Returns the names of the protocol versions which are currently
enabled for use on this connection.
**********
$ javac ProtocolTest.java && java ProtocolTest
Supported Protocols: 5
SSLv2Hello
SSLv3
TLSv1
TLSv1.1
TLSv1.2
Enabled Protocols: 2
SSLv3
TLSv1
