Coherence CE v20.12.1

This is Patch 1 of the Coherence CE v20.12 release.

New Features

• Portable Types

Breaking Changes

• Annotations from the com.oracle.coherence.event package in the main coherence module have been moved back to the com.oracle.coherence.cdi.events package of the coherence-cdi module.
• Most annotations from the com.oracle.coherence.inject package in the main coherence module have been moved back to the com.oracle.coherence.cdi package of the coherence-cdi module.

We apologize for the inconvenience, but this was absolutely necessary to get everything in the right place for the upcoming release of Micronaut and Spring integrations, which unfortunately couldn't reuse the same set of annotations used by the Coherence CDI integration.

Bug Fixes

• Fixed an issue where PrimingListener optimization of NearCache in Coherence*Extend was broken.
• Fixed an issue where DefaultCacheServer.shutdown does not shutdown Coherence server gracefully.
• Enhanced the default SSL HostnameVerifier to be able to verify wild-card Subject Alternate Names and to disable localhost matching by default. Matching of localhost can be enabled via a system property.
• Fixed a race condition between TransferEvent.ASSIGNED and pre-commit EntryEvents. Interceptors registered for TransferEvent.ASSIGNED should fully complete prior to any EntryEvents for the same partition.
• Fixed an issue where distributed service with active persistence was terminated by an async write to an old persistent store.
• Fixed an issue where the Bootstrap API can deadlock if the stop method is called on a Coherence instance before the start up has completed.
• Fixed an issue where loaded entry from CacheStore has inconsistent entry-event type and synthetic flag.
• Excluded Maven build artifacts from distributed library jars.

Improvements

• Synchronized dependencies with Helidon 2.2.1.
• Added SessionConfiguration.create method to Bootstrap API.
• Improved ConverterCollections.getNamedCache to support generics and correctly implement methods putIfAbsent, remove, replace and merge. The return types was widened for some of the factory methods in ConverterCollections to be interface and not implementation based.

Coherence CE v20.12

This is the official Coherence CE v20.12 release including a new API to configure & start Coherence, and faster recovery from disk.

New Features in 20.12:

Bugs fixed since Coherence CE 20.06.1:

• Fixed an issue with the VisualVM Plugin where cache memory bytes could show incorrectly in large clusters.
• Fixed an issue where service could fail to recover a partition repeatedly if persistence enabled and cluster shutdown without suspending first.
• Improved the configuration of the hostname-verifier with the introduction of an "action" element with permitted values of "allow" or "default"; see the XSD for a thorough description.
• Fixed an issue where CacheLifecycleEvents are not emitted for existing caches.
• Fixed an issue where a bad client request could cause a Coherence server to shut down and prevent new servers from joining the cluster.
• Fixed an issue where a service could repeatedly fail to recover a partition.
• Fixed a memory leak of metrics metadata when metrics is enabled.
• Fixed an issue with coherence-json module removing jackson-annotations as a required runtime library.
• Fixed an issue where a custom namespace handler cannot be used within a backing-map-scheme element.
• Fixed an issue where loaded entry from CacheStore has inconsistent entry-event type and synthetic flag.
• Fixed an issue where PartitionedCache's PartitionControl may hang indefinitely due to a discarded backup message.
• Fixed a memory leak which can occur in an *Extend client when using a custom AddressProvider.
• Fixed an issue where a service could be terminated while finalizing a cache request.
• CVE-2020-14756 Fixed an issue where the JEP 290 ObjectInputFilter is bypassed when deserializing an ExternalizableLite object.
• Fixed an issue where the service thread could be terminated while blocked waiting for an index rebuild to finish.
• Fixed an issue where a service with on-demand persistence mode could be blocked by the recovery quorum from a system property.
• Corrected the MANIFEST.MF Bundle-Version in Coherence jar files.
• Fixed an issue where a deadlock could occur when a node becomes the dynamic management senior while there are other management nodes in the cluster.
• Improved recovering from persistence by deferring contentious maintenance tasks.
• Fixed an issue where a cache remove operation could get lost during partition transfer.
• Fixed an issue where NonBlockingFiniteStateMachine.quiesceThenStop() does not shut down the state machine's event processing thread.
• Fixed an issue where partition recovery could take a long time for a large cluster, especially with persistence using shared disk storage.
• Added new attributes starting with Client to ConnectionMBean to identify a Connection to its client when a loadbalancer is between proxy and client. These attributes are mapped to metrics tags on Coherence.Connnection.* metric values.
• Fixed an issue with binary map detection within a ContinuousQueryCache.
• Fixed an issue where partition distribution may fail to reach a balanced state within 5 minutes after recovering from a persistence snapshot.
• Fixed an issue where a NullPointerException could be thrown during partition redistribution.
• Fixed a race condition in ConfigurableCacheFactory where concurrent releaseCache() or destroyCache() calls could result in an IllegalArgumentException being thrown.
• Improved Coherence JVisualVM Plugin to work with 2.0.x versions.
• Fixed an issue with the JVisualVM Plugin where it did not correctly function against Coherence-CE versions.
• Fixed an issue where TcpRing may incorrectly trigger eviction of a temporarily network unreachable cluster member.
• Fixed an issue where partition distribution for a large cluster could take a long time to reach the desired state.
• Added security enhancement that enables configuring between secure static lambdas and more convenient to use dynamic lambdas.
• Coherence now recovers data in parallel within a member/process, in addition to in parallel across the cluster. This allows the cluster, and more importantly the associated data, to be made available as quickly as possible.
• Fixed an issue where a registered MapTrigger may not be called.
