Pool 1.3 has no requirements other than a 1.3 JVM. </p> </li> <li> <p> Thanks to an audit by Mayur Naik many potential synchronizations issues have been fixed. </p> </li> <li> <p> GenericObjectPool and GenericKeyedObjectPool were incorrectly implemented as a LIFO (stack) as opposed to a FIFO as documented. This has been fixed. </p> </li> <li> <p> The PoolUtils class with a number static decorator methods has been added. </p> </li> <li> <p> The following issues were resolved since v1.2: (see Bugzilla for complete description) </p><table class="bodyTable"> <tr class="b"> <th>ID</th> <th>Date</th> <th>Sev</th> <th>State</th> <th>Summary</th> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=27493" class="externalLink" title="External Link">27493</a> </td> <td>2004-11-17</td> <td>enh</td> <td>FIXE</td> <td>GenericKeyedObjectPool: maxTotal limit enhancement</td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=28619" class="externalLink" title="External Link">28619</a> </td> <td>2004-11-17 </td> <td>enh </td> <td>FIXE </td> <td>GenericObjectPool: Swallowed Exception </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=29863" class="externalLink" title="External Link">29863</a> </td> <td>2004-11-17 </td> <td>nor </td> <td>FIXE </td> <td>GenericObjectPool.setMaxActive(0) allows an infinite numb... </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=29912" class="externalLink" title="External Link">29912</a> </td> <td>2004-11-17 </td> <td>nor </td> <td>FIXE </td> <td>[pool] Compilation under 1.5: enum keyword </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=30426" class="externalLink" title="External Link">30426</a> </td> <td>2004-11-17 </td> <td>enh </td> <td>FIXE </td> <td>[pool] need property for removing objects above min </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=31298" class="externalLink" title="External Link">31298</a> </td> <td>2004-11-17 </td> <td>nor </td> <td>FIXE </td> <td>setMinIdle feature implemented for GenericKeyedObjectPool </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=34902" class="externalLink" title="External Link">34902</a> </td> <td>2005-05-16 </td> <td>nor </td> <td>FIXE </td> <td>[pool] StackObjectPool.releaseObject(...) has silly behav... </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=34934" class="externalLink" title="External Link">34934</a> </td> <td>2005-05-16 </td> <td>tri </td> <td>FIXE </td> <td>[pool] clean up some JavaDoc warnings </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=34935" class="externalLink" title="External Link">34935</a> </td> <td>2005-05-16 </td> <td>enh </td> <td>FIXE </td> <td>[pool] changes the borrowObject method so it advoids catc... </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=34296" class="externalLink" title="External Link">34296</a> </td> <td>2005-05-16 </td> <td>maj </td> <td>FIXE </td> <td>[pool] Potential pool leak if _factory.makeObject() throw... </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37226" class="externalLink" title="External Link">37226</a> </td> <td>2005-10-26 </td> <td>maj </td> <td>FIXE </td> <td>[pool] synchronization issues in StackObjectPool </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37227" class="externalLink" title="External Link">37227</a> </td> <td>2005-10-26 </td> <td>maj </td> <td>FIXE </td> <td>[pool] synchronization issues in GenericObjectPool </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37228" class="externalLink" title="External Link">37228</a> </td> <td>2005-10-27 </td> <td>maj </td> <td>FIXE </td> <td>[pool] synchronization issues in SoftReferenceObjectPool </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37234" class="externalLink" title="External Link">37234</a> </td> <td>2005-10-27 </td> <td>maj </td> <td>FIXE </td> <td>[pool] synchronization issues in GenericKeyedObjectPool </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=37235" class="externalLink" title="External Link">37235</a> </td> <td>2005-10-27 </td> <td>maj </td> <td>FIXE </td> <td>[pool] synchronization issues in StackKeyedObjectPool </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=36719" class="externalLink" title="External Link">36719</a> </td> <td>2005-10-29 </td> <td>maj </td> <td>FIXE </td> <td>[pool] Some ObjectPool.borrowObject() implementations do ... </td> </tr> <tr class="a"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=33264" class="externalLink" title="External Link">33264</a> </td> <td>2005-10-29 </td> <td>nor </td> <td>FIXE </td> <td>[pool] GenericObjectPool is a LIFO, not a FIFO implementa... </td> </tr> <tr class="b"> <td> <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=36904" class="externalLink" title="External Link">36904</a>⌨️ 快捷键说明
