RFR: 8263779: SSLEngine reports NEED_WRAP continuously without producing any further output [v2]

[Xue-Lei Andrew Fan]

> As described in the bug, by connecting the SSLEngine with a misbehaving peer SSL implementation, it can get into a state where it calling `wrap` reports getStatus == OK, getHandshakeStatus === NEED_WRAP but still doesn't produce any further output.   It happens when the output bound is not empty.
> 
> The handshake status could have more precise status if the out bound.  The patch was confirmed by the bug submitter.
