Doing this required reworking internal control to use phaser/seqlock-style versioning schemes (affecting nearly every method) that ensure consistent data structures and actions without requiring global synchronization or locking on every task execution that would massively degrade performance. The previous lack of a solution to this was the main reason for these incompatibilities.

Backport instructions:
1. change all methods with new Since tags to nonpublic
2. Comment/uncomment ForkJonPool.invokeAll according to instructions there (the new version fixes an ExecutorService signature incompatibility, at the price of a backwards incompatibility in throws clause.)
3. It is possible that some (incorrect) java/util/concurrent/tck tests will fail, in which case replace with new versions
