24 |
* defining a version of BinaryAsyncAction that uses JDK8 task |
25 |
* tags for control state, thereby testing getForkJoinTaskTag, |
26 |
* setForkJoinTaskTag, and compareAndSetForkJoinTaskTag across |
27 |
* various contexts. Most of the test methods using it are |
28 |
* otherwise identical, but omitting retest of those dealing with |
29 |
* cancellation, which is not represented in this tag scheme. |
