Apache Jackrabbit 2.9.1 发布，Apache Jackrabbit 是由 Apache Foundation 提供的 JSR-170 的开放源码实现.. 随着内容管理应用程序的日益普及，对用于内容仓库的普通、标准化 API 的需求已凸现出来。Content Repository for Java Technology API (JSR-170) 的目标就是提供这样一个接口。JSR-170 的一个主要优点是，它不绑定到任何特定的底层架构。例如，JSR-170 实现的后端数据存储可以是文件系统、WebDAV 仓库、支持 XML 的系统，甚至还可以是 SQL 数据库。此外，JSR-170 的导出和导入功能允许一个集成器在内容后端与 JCR 实现之间无缝地切换。 完整改进记录： Improvements [JCR-3803] Local cache contention lead to performance degradation [JCR-3804] [jackrabbit-aws] Allow http communication to S3 [JCR-3810] StreamWrapper can attempt to reset other types of InputStreams [JCR-3815] Local Cache Purge Cause Performance Issues [JCR-3817] [jackrabbit-aws-ext] Performance of operation degrades while running DS GC [JCR-3818] Use SimpleFSDirectory by default [JCR-3825] Use RepositoryFactory for first hops [JCR-3826] AbstractPrincipalProvider cachesize is not configurable [JCR-3838] [aws-ext] Proactive & Asynchronous caching of binary when its metadata is accessed from S3 [JCR-3843] [jackrabbit-aws-ext] Support S3 in Franfurt Datacenter [JCR-3844] JcrRemotingServlet does not log full stacktrace [JCR-3845] Have AuthorizableQueryManager Support Specifying Sort Ignore Case Mode Bug fixes [JCR-3274] jackrabbit-standalone-2.4.0.jar Populate does not work [JCR-3805] LocalCache doesn't build up properly in JDK 7.
