include some existing java.util Collection interfaces and classes that |

are not part of the spec, but are included because some new methods |

<p>JSR-166 introduces package <code>java.util.concurrent</code> |
| 27 |
|
containing utility classes commonly useful in concurrent |
| 28 |
< |
programming. Like package <tt>java.util</tt>, it includes a few small |

programming. Like package <code>java.util</code>, it includes a few small |
| 29 |
|
standardized extensible frameworks, as well as other classes that |
| 30 |
|
provide useful functionality and are otherwise tedious or difficult to |
| 31 |
|
implement. |

|
A basic (nonblocking) {@link java.util.Queue} interface extending |
| 52 |
|
{@link java.util.Collection} is introduced into |
| 53 |
< |
<tt>java.util</tt>. Existing class {@link java.util.LinkedList} is |
| 53 |
> |
<code>java.util</code>. Existing class {@link java.util.LinkedList} is |
| 54 |
|
adapted to support Queue, and a new non-thread-safe {@link |
| 55 |
|
java.util.PriorityQueue} is added. |

<li> Access checks are no longer required when a Thread interrupts |
| 69 |
< |
<em>itself</em>. The <tt>interrupt</tt> method is the only way to |

<em>itself</em>. The <code>interrupt</code> method is the only way to |
| 70 |
|
re-assert a thread's interruption status (and in the case of |
| 71 |
|
self-interruption has no other effect than this). The check here |
| 72 |
|
previously caused unjustifiable and uncontrollable failures when |
| 73 |
|
restricted code invoked library code that must reassert interruption |
| 74 |

to correctly propagate status when encountering some |

<li> The <code>destroy</code> method, which has never been implemented, |

|
has finally been deprecated. This is just a spec change, reflecting |
| 78 |
|
the fact that the reason it has never been implemented is that |
| 79 |
|
it was undesirable and unworkable. |
