Description
A diagnostic flag was added during the fix to 5075546, in order to revert to the pre-fix functionality (-XX:-UseMembar). Since the change has been incorporated into 38 promotions of J2SE 6.0 and there has been no negative impact related to this new functionality, it is now time to take out this diagnostic option. The removal of this flag should have no negative side affects. In fact there may be a very slight performance improvement in VM runtime calls since we are testing this flag on each transition in and out of the VM for runtime services. ###@###.### 2005-06-01 19:50:01 GMT
