<em> <b>Disclaimer</b>. The prototype implementation is experimental |
| 19 |
< |
code developed as part of JCP JSR-166 is made available to the |
| 20 |

developer community for use as-is. It is not a supported product. Use |
| 21 |

it at your own risk. The specification, language and implementation |
| 25 |
< |
are subject to change as a result of your feedback. Because these |
| 26 |

features have not yet been approved for addition to the Java language, |
| 27 |

there is no schedule for their inclusion in a product. </em> |

<p> <em> <b>Disclaimer</b>. This draft specification was produced |
| 30 |
< |
using JDK1.4 tools plus some preprocessing. The resulting javadocs do |
| 31 |
< |
not yet correctly render other planned JDK1.5 constructs on which |
| 32 |
< |
JSR-166 relies, most notably the use of generic types. We are |
| 33 |
< |
releasing this version now (before the availability of JDK1.5-based |
| 34 |
< |
tools) because, even though they are misformatted and sometimes lack |
| 35 |
< |
proper cross-referencing, they otherwise convey the intended |
| 36 |
< |
specifications. </em> |

<p><em>Note: The javadocs here includes some existing java.util |
| 19 |

Collection interfaces and classes that are not part of the JSR-166 |
| 20 |

spec, but are included because JSR-166 methods implement or inherit |
| 21 |

from their specifications.</em> |

<p> JSR-166 introduces package <tt>java.util.concurrent</tt> |
| 24 |
|
containing utility classes commonly useful in concurrent |
| 25 |
|
programming. Like package <tt>java.util</tt>, it includes a few small |
| 26 |
< |
standardized extensible frameworks, as well as some classes that |

standardized extensible frameworks, as well as other classes that |
| 27 |
|
provide useful functionality and are otherwise tedious or difficult to |

implement. |

|
| 35 |
|
pools. This diversity reflects the range of contexts in which |
| 36 |
|
developers of concurrent programs have been found to require or desire |
| 37 |
|
support not previously available in J2SE, which also keeping the |

<p>Descriptions and brief motivations for the main components may be |

found in the associated package documentation. JSR-166 also includes |

|
<tt>InterruptedExceptions</tt>. |
| 73 |
|
<li> The <tt>destroy</tt> method, which has never been implemented, |
| 74 |

has finally been deprecated. This is just a spec change, reflecting |
