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.

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.
23. `COH-3042...

13. COH-29598 Improved the process of loading management-config.xml so that the file can be overridden by placing another management-config.xml file in the classpath or module path before coherence.jar.

Bugs fixed since Coherence CE 24.03

1. COH-30427 Fixed an issue where version compatibility checks could fail when parsing CE versions which could manifest as serialization compatibility exceptions when doing a rolling upgrade.
2. COH-30319 Fixed an issue where the Coherence health API could report ready before all services had started.
3. COH-30247 Fixed an issue where the coherence.distributed.partitioncount system property was not honored when using the default cache configuration.

6. COH-30157 Fixed an issue where the cluster service may be stopped in very rare circumstances due to an unhandled UnsupportedOperationException.
7. COH-30067 Fixed an issue where CacheMappingRegistry.register() or SchemeMappingRegistry.register() will throw a NullPointerException if the registry is not initialized.
8. COH-30023 Fixed an issue where, in certain cases, remote invocation using an ArrayFilter would use excessive CPU.
9. COH-30006 Fixed an issue where topic subscribers could become disconnected and hang attempting to reconnect. The fix for this issue means that when using topics is it not possible to perform a rolling upgrade from versions prior to 14.1.1-2206-4. If a rolling upgrade is required it must be done in two stages, first to a version 14.1.1-2206-4 or higher then to the 14.1.1-2206-9. This rolling upgrade restriction only affects applications that are using topics.

Known Issues

Due to earlier incompatibility issue with 22.06 and 22.06.1 releases, it is not possible to do a rolling upgrade directly from those releases to this patch set.

You can however do this rolling upgrade in two phases:

1. 22.06 or 22.06.1 -> 22.06.2
2. 22.06.2 -> current patch set

For more information on pre-requisites for performing a rolling restart, see the 14.1.1.2206 documentation

While a Coherence gRPC server and client still work in a Helidon application, it is no longer possible to automatically serve Coherence gRPC proxy endpoints on the Helidon MP gRPC server. Coherence configures and creates its own independent gRPC clients and server.

Bugs fixed since Coherence CE 22.06.7

25. COH-28548 Fixed a rare issue with the executor service where a dynamically registered executor could result in an inflight task not completing.
26. COH-28485 Fixed QueryMap.values methods that accept Filter argument to eliminate eager deserialization of returned values when called against distributed cache, to bring them in-line with the existing keySet and entrySet implementations, which deserialize returned results lazily.

Coherence CE 24.03

This is the Coherence CE v24.03 release.

Requirements:

• Java 17 or higher
• Some features will work only on Java 21 or higher

New Features in CE 24.03

Coherence CE 24.03 is now compatible with both Helidon 3.x and Helidon 4.x.

1. COH-29737 Improved deserialization performance of very large byte arrays (> 100MB)
2. COH-29199 Added the ability to configure the number of worker threads used by the concurrent cache service using system properties: coherence.concurrent.distributed.threads.{min|max}. The concurrent cache service will honor the global system properties coherence.distributed.threads.{min|max} if provided and the concurrent cache specific system properties are not set.
3. COH-29020 Added additional columns to the memory status report to show memory information in megabytes. Additionally ensured that in all reports the display of report values never uses exponential notation.
4. COH-28849 Added the ability to pass a custom Executor to AsyncNamedCache to use to complete the invoked futures instead of using the Coherence common pool. This is useful if it is a requirement to strictly enforce order of completion of async futures.
5. COH-28810 Added a message to stdout which prints the Coherence logging configuration when the Coherence logger is set to level 6 or higher.
6. COH-28809 Reduced the frequency of the messages displayed (to once every 60 seconds) when the BinaryMemoryCalculator cannot calculate the index size.
7. COH-28726 An internal ForkJoinPool is now used to run queries in parallel across all owned partitions.
8. COH-28725 Improved the Coherence Gradle Plugin POF instrumentation support for multi-module Gradle builds.

Breaking changes in CE 24.03

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

• COH-28501 Removed the coherence-helidon-grpc, coherence-helidon-client and coherence-helidon-proxy modules. While a Coherence gRPC server and client still work in a Helidon application, it is no longer possible to automatically serve Coherence gRPC proxy endpoints on the Helidon MP gRPC server. Coherence configures and creates its own independent gRPC clients and server.
