Coherence CE 24.03

[aseovic]

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.
9. COH-28615 The distributed executor service will now distribute tasks to executors in a round-robin fashion.
10. COH-28601 Integrated support for OpenTelemetry. See the documentation for further details.
11. COH-28572 Re-enabled the Coherence Gradle Plugin, upgraded to Gradle 8.4 and provided Java 21 support.
12. COH-28552 Improved the filter reordering logic for composite filters.
13. COH-28550 Improved performance of filter-based aggregators by leveraging partitioned index.
14. COH-28549 Improved performance of filter-based entry processors by leveraging partitioned index.
15. COH-28458 Fixed an issue where JPMS --add-exports java.management/sun.management=com.oracle.coherence was required when using Berkeley Database JE database for storage, enabled by bdb-store-manager, as documented in section "Using Java Modules to Build a Coherence Application".
16. COH-28314 Added the ability to insert JSON data via CohQL.
17. COH-28004 Fixed "Started Cluster" log message to clarify that a JOINING member's version is a transport protocol compatibility version, not the member's actual Coherence version.
18. COH-27990 Added the ClearCount attribute to the StorageManager MBean which shows how many times clear() has been called on a cache.
19. COH-27952 Enhanced the Gradle plugin to provide incremental build support for POF classes.
20. COH-27105 Added the reportPartitionStats operation to the StorageManager MBean to report cache partition sizes for a cache.
21. COH-25882 Added getClusterDescription, getServiceDescription and getNodeDescription operations to the Cluster, Service and ClusterNode MBeans to retrieve details about a cluster, service and member.
22. COH-25729 Added write-behind support for cache store erase() and eraseAll() operations.
23. COH-24445 Added cache backed implementations of java.util Queue and Deque and java.util.concurrent BlockingQueue and BlockingDeque.

For more information see the Core Improvements documentation.

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.

Bugs Fixed since Coherence CE 23.09

40. COH-28721 Fixed an issue where near cache key lock(s) were not being properly released when the back map is truncated and the near cache is using the PRESENT invalidation strategy. The observable failure is thread(s) hung waiting for near cache key locks that are never released.
41. COH-28705 Fixed an issue where a RequestTimeoutException may be thrown when setting an MBean attribute due to the operation using a small timeout value instead of the service request timeout.
42. COH-28652 Fix a performance regression by removing unnecessary JEP-290 filter checking of the array length of a String or Binary.
43. COH-28648 Fixed an issue in OpenTelemetry support that would allow the tracing runtime to be re-initialized when being disabled dynamically via JMX.

47. COH-28547 Fixed an issue where using a conditional index on a key extractor resulted in the corresponding index not being updated when entry values were modified, and queries would return incorrect results.
48. COH-28538 Fixed a race condition which could cause a PagedTopic to miss messages when cancelling futures returned by a subscriber.
49. COH-28536 Fixed an issue where a race condition is possible in SafeHashMap on ARM processors.
50. COH-28507 Removed the Sun Codemodel shaded dependency from coherence.jar due to its dropped support in Java 17.
51. COH-28485 Fixed QueryMap.values() methods that take a Filter argument to eliminate eager deserialization of returned values when called against partitioned cache, to bring them in-line with the existing keySet() and entrySet() implementations, which deserialize returned results lazily.
52. COH-28484 Fixed an issue that prevents ExtractorComparator to be used with PofExtractor.
53. COH-28461 Fixed an issue where UnsolicitedCommitEvents may not fire for some entries which are part of a bulk update such as a clear().
54. COH-28336 Fixed an issue in OpenTracing integration where a NullPointerException may be thrown if the tracing propagation state is empty.
55. COH-28279 Changed async() to throw an UnsupportedOperationException for Extend caches. Changed async() for near and view caches to call async() on the back cache.
56. COH-28096 Fixed an issue where query results could include an entry that does not match specified filter under heavy concurrent updates.
57. COH-28095 Removed obsolete coherence-metrics.jar. Coherence metrics functionality is included in coherence.jar.
58. COH-28074 Fixed an issue where partitioned queries took longer to execute than before, this fix now provides as fast or faster execution due to the ability to run queries in parallel across partitions.
59. COH-25354 Fixed a rare issue in the executor service where a task executing across multiple members may not complete properly.
