Coherence CE 24.09 is now compatible with both Helidon 3.x and Helidon 4.x.

  1. COH-30940 Added new ValueExtractor factory methods to the com.tangosol.util.Extractors class.
  2. COH-30800 Narrowed down the return type of factory methods in Extractors class to eliminate the need for casting of created extractor instances.

  4. COH-30793 Narrowed down the return type of factory methods in Aggregators class to eliminate the need for casting of created aggregator instances.
  5. COH-30743 Introduced a distributed paged queue that does not have the 2GB size limit of the simple Coherence queue.
  6. COH-30731 Added CollectionExtractor which enables projection of values within a collection using a nested ValueExtractor.
  7. COH-30715 Added a debug system property coherence.debug.operational.config that when set to true, causes Coherence to dump the stack of the thread that loads the Coherence operational config to standard out.
  8. COH-30690 Enhanced the com.tangosol.net.Coherence class main method to be consistent with DefaultCacheServer main method.
  9. COH-30627 Added support for high-performance (raw) serialization of primitive arrays.

  16. COH-30388 Fixed rolling upgrade for distributed lambdas by removing production mode defaulting to static lambdas.
  17. COH-30385 Narrowed down the return type of factory methods in Filters class to eliminate the need for casting of created filter instances.
  18. COH-30322 Marked generated __evolvableHolder$ field as @JsonbTransient, to avoid its serialization into JSON output when using JSONB to serialize portable types.
  19. COH-30308 Added a new append method to the NamedQueue API to add an element to a queue and return a numeric identifier for the added element.
  20. COH-30158 Added Listener Key Count, Listener Filter Count and Listener Registration Count to report-cache-storage.xml.
  21. COH-30148 Added support to allow the definition of custom executors for the remote executor service via XML configuration.
  22. COH-30142 Added support for advanced task orchestration across multiple JVMs via the RemoteExecutor API.

  32. COH-29757 Reduced the overhead of key set manipulation when applying indexes.
  33. COH-29737 Improved deserialization performance of very large byte arrays (> 100MB).
  34. COH-29676 Improved the process of loading management-http-config.xml so that the file can be overridden by placing another management-http-config.xml file in the class path before coherence.jar.

Breaking changes in Coherence CE 24.09

The following lists subset of bugs fixed that are considered "breaking" changes:

  1. COH-30699 Fixed an issue where the id property of the @PortableType annotation was not mandatory and could lead to issues with serialization compatibility and schema evolvability. This is a breaking change and requires a unique 'id' attribute to be set on all usages of the annotation.

Bugs Fixed since Coherence CE 24.03

  1. COH-31000 Updated Protocol Buffers (protobuf) version to 3.25.5.
  2. COH-30969 Fixed an issue where InFilter queries could take longer to return.
  3. COH-30950 Fix equality and hashCode for UniversalExtractor(UE), used by indexing, when UE name is a JavaBean accessor but missing method suffix, "()", , i.e. UE("getProperty") is now equivalent to UE("getProperty()") and ReflectionExtractor("getProperty").
  4. COH-30939 Fixed a thread safety issue when calling removeAll on SafeHashMap.
  5. COH-30928 Updated the executor services CronTask to allow the user to configure whether or not the wrapped task should be cloned upon each successful execution or not where as previously, it always performed the clone which prevents the task from maintaining internal state.
  6. COH-30916 Fixed an issue where performing a rolling upgrade would cause a NullPointerException and make the cache service restart.
  7. COH-30907 Fixed an issue that prevented the use of additional filters when using NamedOrchestration to orchestrate tasks to the executor service.
  8. COH-30845 Fixed an issue where entry processor invocations may never be re-sent when re-distribution takes place at the same time.
  9. COH-30841 Deprecated ImmutableArrayList.getSortedSet for removal. Both this method and the SortedSet interface implementation will be removed from ImmutableArrayList in a future release.
  10. COH-30830 Fixed an issue where ContinuousQueryCache did not handle NamedCacheDeactivationListener registrations correctly. This can cause issues if using View Scheme on Extend or gRPC Proxy servers.
  11. COH-30828 Fixed an issue where the history file was not getting saved to disk for CohQL query console & Coherence console when using jline.jar.
  12. COH-30804 Enhanced the service startup messages for Partitioned, Invocation and Proxy services to display the serializer used.
  13. COH-30782 Fixed an issue when using Coherence with Helidon 4.x where you could get filter status REJECTED message.
  14. COH-30762 Fixed an issue where a rolling upgrade was not possible in some cases when using view caches due to a version compatability issue.
  15. COH-30735 Bumped the Helidon 3 version to 3.2.9.
  16. COH-30646 Fixed regression in CohQL query.sh by adding new command line argument "-v" to indicate that the CohQL statement should be echo'ed to output. Also fixed unhandled JLine exceptions for EOF and user interruption.
  17. COH-30570 Added an additional property (pofIndexPackages) to the Coherence Gradle plugin to limit the Java packages to scan (by providing 1 or more package names) when indexing @PortableType-annotated classes.
  18. COH-30539 Fixed an issue where the forceRecovery operation was not present in the management-swagger.json for Management over REST
  19. COH-30533 Fixed an issue where specifying a wrong value for persistence mode would be silently ignored and default to on-demand.
  20. COH-30472 Fixed an issue where deserialization of reflection based extractors may be rejected when running in WebLogic.
  21. COH-30438 Fixed an issue that resulted in unnecessary deserialization of entry values during write-behind.
  22. COH-30431 Removed an unnecessary stack trace that is logged when an Extend connection is closed.

  29. COH-30247 Fixed an issue where the coherence.distributed.partitioncount system property was not honored when using the default cache configuration.
  30. COH-30209 Fixed an issue where rolling restart with persistence done concurrently by 2 or more nodes may result in the cache service going into the ORPHANED state and require a cluster restart.
  31. COH-30178 Fixed an issue which could prevent tasks from being executed by RemoteExecutors.
  32. COH-30157 Fixed an issue where the cluster service may be stopped in very rare circumstances due to an unhandled UnsupportedOperationException.

  34. COH-30067 Fixed an issue where CacheMappingRegistry.register() or SchemeMappingRegistry.register() will throw a NullPointerException if the registry is not initialized.
  35. COH-30023 Fixed an issue where, in certain cases, remote invocation using an ArrayFilter would use excessive CPU.
  36. COH-30006 Fixed an issue where topic subscribers could become disconnected and hang attempting to reconnect.
  37. COH-29996 Fixed an issue where the expiry delay was ignored when calling put on a cache using the gRPC API with a Helidon 4 gRPC proxy server.
  38. COH-29822 Fixed an issue where XSD schema validation may fail in coherence-operational-config.xsd when using JDK22 or greater and setting -Djdk.xml.jdkcatalog.resolve=strict.
  39. COH-29808 Updated Netty to version 4.1.108.Final.
  40. COH-29765 Fixed an issue where multiple long running tasks may prevent other tasks from being executed by concurrent Executors.

  46. COH-26683 Fixed an issue where MessageBus would heartbeat at double the configured interval.
  47. COH-25080 Fixed an issue where persistence files could become corrupted and hamper recovery in the event of an ungraceful shutdown.
  48. COH-24703 Removed an unnecessary stack trace that is logged when a member leaves a cluster.
  49. COH-23555 Fixed an issue where near, view, and continuous query caches may contain stale data after snapshot recovery.
