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.
