Coherence CE v21.12.2

This is Patch 2 of the Coherence CE v21.12 release.

Bugs fixed since Coherence CE 21.12.1:

• Enhanced Coherence REST server logging to assist development time debugging, log handled exceptions for REST HTTP Response of BAD_REQUEST (status 400) at log level 6 or higher.
• Added ServiceMBean attribute StatusHACode for metrics support.

New Features in 21.12.1:

• Added support for using a password provider for the keystore password in the AccessController.
• Added API methods to determine the number of unreceived elements for a NamedTopic subscriber or subscriber group.

Bugs fixed since Coherence CE 21.12:

• Fixed an issue with AccessController where keystores which support read access without a password could no longer be used without a password.
• Removed the optional Log4J and SLF4J dependencies from the Coherence POM file.
• Fixed an issue where topic subscribers failed to be cleaned up causing channels to fail to be reallocated to remaining subscribers.
• Fixed an issue where deadlock occurs if a topic and one or more of its publishers are closed by different threads at the same time.

• Updated the management Swagger to call out certain features that are available when using Grid Edition only.
• Fixed an issue in topic Subscriber where the CompletableFuture returned from calls to Subscriber.receieve() could fail to complete on an empty topic when the Subscriber was created with the CompleteOnEmpty option enabled.
• Fixed an issue where the operationId in the management Swagger document was incorrect for the stop service operation.

Coherence CE v14.1.1.0.8

This is patch 8 of the Coherence CE v14.1.1 release.

Bugs fixed since Coherence CE 14.1.1.0.7:

• Fixed an issue where setting discovery-address in multicast mode did not have any effect. The specified address will now be used as the discovery endpoint. If a discovery-address is not specified, by default the discovery endpoint will bind to all interfaces on a multi-homed machine.
• Fixed an issue where a null was returned in a JFR status message instead of the actual member id.
• Added the ability to register lifecycle listeners with DefaultCacheServer instances, either via the DefaultCacheServer API, or via discovery using the Java ServiceLoader.
• Fixed a regression in PortableException when Java serialisation introduced in 12.2.1.4.5 and 14.1.1.0.1 that made it incompatible with earlier Coherence versions. Applications using POF are not affected by this change or this bug.
• Fixed an issue where requests could hang indefinitely due to a failed partition recovery.

• Improved startup times in OSs that exhibit slow times in deriving the network interface associated to an IP address.

Coherence CE v21.12

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.
  • An ExecutorService implementation allowing guaranteed remote task execution.
• Backup Improvements
  • Allow the redundant copies to be used for reads (get/getAll) with the option of choosing primary, closest, a random backup up, or provide your own implementation.
  • Reduce the cost of asynchronous backups, thus improving write throughput, by scheduling the changes to be sent to redundant copies periodically.

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
• Fixed an issue where a client side memory leak may occur when many TopicPublishers are created and closed with option FailOnFull.enabled().

• Fixed a regression in PortableException when Java serialization introduced in 12.2.1.4.5 and 14.1.1.0.1 that made it incompatible with earlier Coherence versions. Applications using POF are not affected by this change or this bug.
• 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 topic subscribers could create a deadlock when reconnecting after loss of storage members, causing the service guardian to terminate the service .
• Fixed an issue where requests could hang indefinitely due to a failed partition recovery.
• 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 stream collect on NamedCache collections (keySet, values, entrySet) throws UnsupportedOperationException.

• 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.

• 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.
