<em> <b>Disclaimer</b>. The prototype implementation is experimental |

code developed as part of JCP JSR-166 is made available to the |

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

it at your own risk. The specification, language and implementation |
22 |

are subject to change as a result of your feedback. Because these |

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

<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 do <em>not</em> include pre-existing |
19 |

java classes (for example <tt>java.lang.Thread</tt>) that were changed |
20 |

as part of the JSR166 spec. On the other hand, the javadocs here do |
21 |

include some existing java.util Collection interfaces and classes that |
22 |

are not part of the spec, but are included because some new methods |
23 |

implement or inherit from their specifications. |
