Bug

[ ISPN-2145 ] - No descriptions for invalid jgroups configuration files
[ ISPN-5322 ] - A WARN message is shown that Partition Handling is not supported in REPL mode
[ ISPN-5434 ] - ClusteringConfigurationBuilder.l1() javadoc incorrectly states that the l1 method enables l1
[ ISPN-5436 ] - Some ClientClusterEventsTest tests fail randomly
[ ISPN-5448 ] - NPE when configuring both SSL and authentication in the same fluid configuration API for HotRod
[ ISPN-5449 ] - java.lang.ClassCastException: [B cannot be cast to org.infinispan.container.entries.CacheEntry
[ ISPN-5450 ] - Remote queries fail when security is enabled and current user is not an ADMIN
[ ISPN-5455 ] - NullPointerException when running a script
[ ISPN-5460 ] - Prepare commands sent before the target became a member should be rejected
[ ISPN-5462 ] - Transaction prepare is not replicated to new owners during state transfer
[ ISPN-5463 ] - ClassCastException: org.infinispan.query.remote.indexing.ProtobufValueWrapper cannot be cast to [B
[ ISPN-5464 ] - ReflectionHelper fails to detect element type for arrays of generic types
[ ISPN-5474 ] - Transactions created when applying state should never be replicated
[ ISPN-5477 ] - Compatibility with L1 can lead to wrong return type
[ ISPN-5483 ] - JGroupsTransport.waitForChannelToConnect() never waits; fetchRebalancingStatusFromCoordinator() is susceptible to NPE
[ ISPN-5486 ] - SemaphoreCompletionService exceptions are never checked
[ ISPN-5490 ] - Cache.clear() does not clear the cache store with async store
[ ISPN-5494 ] - Node replies with NullPointerException during shutdown
[ ISPN-5501 ] - Camel throwing java.lang.LinkageError for Remote Query when running in EAP
[ ISPN-5502 ] - Build fails with JDK7

Enhancement

[ ISPN-5165 ] - Cannot choose to run index-less query on an indexed cache
[ ISPN-5389 ] - Optimize overlapping range and interval predicates (non-indexed query)
[ ISPN-5461 ] - FileDescriptorSource.fromResources and FileDescriptorSource.addProtoFiles should have a ClassLoader argument

Task

[ ISPN-3924 ] - Fix test: NonTxPutIfAbsentDuringLeaveStressTest.testNodeLeavingDuringPutIfAbsent:114

Inﬁnispan 是个开源的数据网格平台。它公开了一个简单的数据结构（一个Cache）来存储对象。虽然可以在本地模式下运行Inﬁnspan，但其真正的价值在于分布式，在这种模式下，Inﬁnispan可以将集群缓存起来并公开大容量的堆内存。这可比简单的复制强大的多，因为它会为每个结点分配固定数量的副本——服务器故障的一种恢复手段——同时还提升了可伸缩性，这是由于存储每个结点所需的工作量是与集群大小息息相关的。

Infinispan 7.2.2.Final 发布，数据网格平台

Inﬁnispan 提供了一种简单的机制来利用大容量的堆内存。如果对每个结点维护一个拷贝，假如集群当中有100个结点，每个结点分配2GB的堆内存，那么网格中的任何实例都能使用多达100GB的空间，这可都是内存，显然速度会非常快。同时Inﬁnispan还兼容于JTA，这样它就能很好地处理事务了。我们还有一个超级强大的异步API，它可以保证同步的网络调用以及异步调用的并行性及可伸缩性。比方说：Future f = cache.putAsync(k, v) 可以阻塞线程，再调用f.get()可以让网络调用继续进行或是忽略掉f。更为重要的是，线程还可以做别的事情，这一点非常有用。然后再回来通过调用 f.get()来检查该网络调用是否能继续进行。可以将其看作是NIO与传统的阻塞性IO之间的关系。

Inﬁnispan公开了一个 CacheStore接口和几个高性能的实现，包括JDBC CacheStores、基于文件系统的CacheStores以及Amazon S3 CacheStores等等。CacheStores可用作“温启动（warm starts）”或是确保网格中的数据在重启后依然可用，同时在内存耗尽时还能将数据写到磁盘上。
