Coherence CE v22.06

This is the official Coherence CE v22.06 release.

New Features in 22.06:

• Java Modules Support - You can now run Coherence using Java modules.
• Topics Improvements
  • A number of durability and stability improvements have been applied to make topics more stable during fail-over.
  • Topics now guarantee at least once delivery, where as in previous releases this was not the case. A subscriber that is part of a group can commit a processed message to indicate that processing is complete and it should not be redelivered on fail-over.
  • Subscribers that are part of a subscriber group are now fairly allocated topic channels to subscribe from; only a single subscriber receives messages from an allocated channel.
  • Subscribers will be timed-out after a configurable period of inactivity (or failure to heartbeat) causing their channels to be reallocated to remaining subscribers in the same group.
  • Added API methods to determine the number of unreceived elements for a NamedTopic subscriber or subscriber group.
• Caffeine - Coherence now adds a Caffeine backing map implementation, enabling you to use Caffeine wherever the standard Coherence local cache can be used.
• Cache Configuration Override - Similar to the Coherence Cluster override, you can now specify a cache configuration override to override elements of existing cache configuration with new elements at runtime.
• BigDecimal-related aggregators - These aggregators now support the ability to set BigDecimal properties such as scale, roundingMode, stripTrailingZeros, and mathContext (where applicable) for the final result.
• Persistent Backups - You can now enable and configure persistent backups which stores backup partitions on a disk, as additional copies of persisted primary one.
• POF Configuration Discovery - It is now possible to make POF configuration files discoverable at runtime by the ConfigurablePofContext class instead of needing to put them inside <include> elements.
• Support for MEMBER_JOINED and MEMBER_LEFT events for Extend clients - Extend proxy now sends MEMBER_JOINED and MEMBER_LEFT events to all active services on the proxy when a remote client joins and leaves. This event enables management of a service’s server side resources being retained per remote client. If a MemberListener is registered on a service and the environment has both remote and cluster member access to a service, the MemberListener may need to account for remote client MemberEvent(s).
• SSL Improvements - Various SSL improvements that enable more flexible configuration and allow customizations through extensions. These include using private key and certificate files, using custom keystore, private key and certificate loaders, which can also be refreshable.
• Locks and Semaphores can now be accessed via Coherence*Extend Java clients.
• Health Check API - A new health check API to enable application code to determine the health of the local Coherence member. Management over REST has also been updated to support the health check API.
• New Reports - Executor, View, Storage, and Proxy Connections.

This is the official Coherence CE v21.12 release including the following new features.

New Features in 21.12:

• Distributed Concurrent Data Structures
  • Distributed implementations of java.util.concurrent primitives, such as atomics, locks, latches and semaphores.

Bugs fixed since Coherence CE 21.06:

• Fixed an issue where a service could be terminated during partition recovery due to guardian timeout.
• Fixed an issue where service names and other path elements were not being validated in Management over REST endpoints

• Improved the removal of topic group subscribers created by departed cluster members, by making it more aggressive and hence speeding up reallocation of channels to the remaining subscribers.
• Fixed an issue where topic subscribers could cause a deadlock when processing non-empty channel notifications.
• Fixed an issue where member departure caused all topic subscribers on storage disabled members to be disconnected instead of just cleaning up departed subscribers.

• Fixed an issue where UnitsBytes could be negative when unit factor was greater than one.
• Bumped the version for JLine dependencies and included JLine jar files.
• Fixed an issue where a distributed service could release an unowned partition leading to IllegalStateException.
• Enhanced the Coherence.start() method, released as part of the Bootstrap API in CE version 20.12, to return a CompletableFuture<Coherence> instead of a CompletableFuture<Void>. This allows a more fluent API when using static factory methods to create and start a Coherence instance. This is a breaking change in applications that specifically assign the result of calls to Coherence.start() to a CompletableFuture<Void> variable.
• Fixed an issue where a service could hang indefinitely on updateIndex waiting for pending storage version to commit.
• Fixed an issue where CohQL could return incorrect results when compound conditions are used with parenthesis on the first part of the query statement.

• Fixed an issue where a topic subscriber with only a single channel allocated will not stop polling even when the channel is empty.
• Added example showing how to monitor StatusHA for rolling redeploys
• Fixed an issue where the Java gRPC client will hang when getting caches if no connection to the server can be made.
• Fixed an issue with cluster start up when a unicast-listener/discovery-address is specified in multicast mode.
• Fixed an issue where if an initial event is not received for a partition DurableEvents will miss events that occurred while being disconnected.

• Fixed an issue where the partitioned cache service thread could hit the guardian timeout while processing deferred events during partition recovery or failover.
• Fixed an issue where CohQL persistence commands may throw an IllegalArgumentException.
• Improved startup times in OSs that exhibit slow times in deriving the network interface associated to an IP address.
• Improved the partition transfer process to work more efficiently while the service is under heavy load.
• CVE-2021-2344 Fixed an issue where Java array deserialization may be used for a denial of service attack using malicious bytecode sent via WLS T3 and IIOP protocols.
• CVE-2021-2371 Fixed an issue where Java array deserialization using ExternalizableHelper may be used for a denial of service attack using malicious bytecode sent via WLS T3 and IIOP protocols.
• Fixed an issue where cluster join may automatically fallback to multicast if all of the configured WKA addresses are unresolvable.
• Added ILIKE operator to CohQL; the case-insensitive equivalent of LIKE

• Fixed an issue with serializing classes annotated with PortableType that have not specified an ID.
• Enhanced Coherence metrics to allow metric names to be published without a vendor: prefix. Removing the vendor: prefix is controlled by setting the system property coherence.metrics.legacy.names=false
• Moved Coherence metrics functionality into coherence.jar, removing the requirement to use coherence-metrics.jar and removing the requirement for additional third-party dependencies when enabling Coherence metrics. 
• Enhanced CohQL to handle the case where value() is used in where clauses.
• Fixed a thread safety issue that can disrupt a joining member from joining the service in very rare cases.
• Fixed an issue when there are multiple cache factories in a JVM, the cache factory created the proxy service may not be the one used by it, resulting in error finding the caches.
• Fixed an issue where CacheStore.eraseAll() had no path to be called on NamedCache bulk operations such as invokeAll(). With this fix, CacheStore.eraseAll() is called when NamedCache.invokeAll() is invoked with a "remove" processor or when NamedCache.keySet().removeAll() or NamedCache.entrySet().removeAll() are called.
• Reduced CPU utilization in sending backup messages
• Bumped the version of Jetty dependency to 9.4.43.v20210629.
• Fixed an issue where changing the Coherence log level using the Node Mbean had no effect.
