Coherence CE v14.1.1.0.7

This is patch 7 of the Coherence CE v14.1.1 release.

Fixed Issues

• Fixed an issue where stream collect on NamedCache collections (keySet, values, entrySet) throws UnsupportedOperationException.
• Fixed a NullPointerException that occurred when generating a log message after failing to start management over REST, which resulted in the misleading, and non-helpful, error log message: "Failure to initialize JMX remote management caused by: NullPointerException".
• Fixed an issue where expired entries are not evicted for ReadWriteBackingMap.
• Fixed an issue that class ConverterComparator is serializable, which is not required.
• Added additional logging when metrics registration fails.
• Fixed an issue in management over REST where the services list returns an HTTP 500 error when the cluster has no services.
• Fixed an issue where NullPointerException could occur in the index rebuild thread during failover, and lead to worker threads hanging waiting for index ready.
• Added cache configuration element cache-values which allows a view-scheme to be configured to cache both keys and values (the default), or only keys.
• Fixed an issue with cluster start up when a unicast-listener/discovery-address is specified in multicast mode.
• Fixed an issue in persistence to ensure errors are caught in a rare and unexpected part of the recovery protocol.
• Fixed an issue where session invalidation might lead to "no usable session model error" and stuck threads.
• Fixed an issue where CohQL persistence commands may throw an IllegalArgumentException.
• Improved the partition transfer process to work more efficiently while the service is under heavy load.

Coherence CE v21.06.2

This is Patch 2 of the Coherence CE v21.06 release.

Fixed Issues

• Improved 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 a NullPointerException that occurred when generating a log message after failing to start management over REST, which resulted in the misleading, and non-helpful, error log message: "Failure to initialize JMX remote management caused by:NullPointerException".
• Fixed an issue where expired entries are not evicted for ReadWriteBackingMap.
• Fixed an issue that class ConverterComparator is serializable, which is not required.
• Fixed issue where the management over REST Endpoint to list services in a cluster returns a HTTP 500 error when the cluster has no services
• Fixed an issue where NullPointerException could occur in the index rebuild thread during failover, and lead to worker threads hanging waiting for index ready.
• Fixed an issue with cluster start up when a unicast-listener/discovery-address is specified in multicast mode.
• Fixed an issue where CohQL Persistence commands may throw a IllegalArgumentException.
• Fixed a memory leak that occurred when creating and releasing topic publishers and subscribers
• Added example showing how to monitor StatusHA for rolling redeploys
• Fixed an issue where if an initial event is not received for a partition DurableEvents will miss events that occurred while being disconnected.
• Improved Coherence metrics by removing external dependencies and relocating the code into the core coherence.jar, thereby removing the need for projects to depend on coherence-metrics, which is now an empty jar.
• Improved the reallocation of topic subscriber channels by triggering this immediately on member departure instead of waiting for departed subscribers to timeout.
• Improved and hardened topic subscriber channel allocation notification.
• Improved the algorithm used to distribute channels to subscribers in a topic subscriber group to produce a more even distribution.
• Enhanced Coherence metrics to allow metric names to be published without a vendor: prefix which is controlled by setting the system property coherence.metrics.legacy.names=false.

Coherence CE v21.06.1

This is Patch 1 of the Coherence CE v21.06 release.

• Fixed an issue where an ArrayIndexOutOfBoundsException could be thrown when using the PortableType annotation.
• Fixed an issue in persistence to ensure errors are caught in a rare and unexpected part of the recovery protocol.
• Fixed an issue where a topic subscriber with only a single channel allocated will not stop polling even when the channel is empty.
• Fixed an issue where the Java gRPC client will hang when getting caches if no connection to the server can be made.
• CVE-2021-2428 Fixed Java serialization of the Coherence JCache CoherenceEntryProcessorResult class to prevent unintended usage of this class.
• 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.
