|
* defining a version of BinaryAsyncAction that uses JDK8 task |
25 |
|
|
* tags for control state, thereby testing getForkJoinTaskTag, |
26 |

* setForkJoinTaskTag, and compareAndSetForkJoinTaskTag across |

* various contexts. Most of the test methods using it are |

29 |

* cancellation, which is not represented in this tag scheme. |
