> Run SyncTest using 2 different bbp algorithms:
> For BBP.version=1 (needs HARMONY-2056 to work correctly)
> java.exe -Xem:opt -Djit. f.arg.codegen.bbp.version=1  -Djit.CS_OPT.f.filter=Waiter::run -Djit.f.arg.log=ct,irdump,dotdump -Djit.CS_OPT.arg.optimizer.inliner=off SyncTest
> waiter started..
> stopper started..
> stopping..
> inside finish()..
> stopped..
> passed!
> For BBP.version=6
> java.exe -Xem:opt -Djit. f.arg.codegen.bbp.version=6  -Djit.CS_OPT.f.filter=Waiter::run -Djit.f.arg.log=ct,irdump,dotdump -Djit.CS_OPT.arg.optimizer.inliner=off SyncTest
> waiter started..
> .....(hangs..)
> If you check the IR you will see that for version=6 there was no BBP code insertion into the loop with monenter and monexit helpers.
