[jdk8u-dev] Request for approval and review: 8209129: Further improvements to cipher buffer management

[Seán Coffey]

I'm looking to port this fix to jdk8u-dev. Fix already pushed to JDK 12. 
The patch applied almost cleanly. There was some minor failure 
concerning the insertion of import statements at top of files IIRC.
