JCEEncryptor.java needs to adapt to JDK9+ change of JCE provider needing explicitly initialization for each use

[himan-k]

We are having to init a cipher everytime we encrypt password now - a functionality provided through JCEEncryptor.java. The current implementation is incompatible with new JCE semantics though, so we have to explicitly init the cipher before it gets used since doFinal seems to unload the cipher. As a result, you cannot encrypt a password again once doFinal has been called on it.

Anyone know what I am talking about? Shouldn't this be fixed in EclipseLink code already?
