[11u] RFR: 8256452: Integrate missing part of JDK-8232370 to 11u

[Langer, Christoph]

Hi,

please review this 11u only change.

JDK-8232370 [0] had been backported before JDK-8210560 [1]. So, at the time, the update for RedefineImplementor.java was omitted since that file was only introduced with JDK-8210560. Now, after the latter was backported, we should also update RedefineImplementor.java to get the IDE green again.

Bug: https://bugs.openjdk.java.net/browse/JDK-8256452
Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8256452.11u/
Original Change (JDK-8232370): https://hg.openjdk.java.net/jdk/jdk/rev/5f14a659a8cb

Thanks
Christoph
