This is the Coherence CE v25.03 release.
Requirements:
- Java 17 or higher
- Some features will work only on Java 21 or higher
Major New Features in Coherence CE 25.03
- Remote Topics
A remote topic is specialized topic service that routes operations to a topic on the Coherence cluster. The remote topic and the topic on the cluster must have the same topic name. Extend clients use theNamedTopicinterface as normal to get an instance of the topic. At run time, the topic operations are not executed locally but instead are sent using TCP/IP to an Extend or gRPC proxy service on the cluster. The fact that the topic operations are delegated to a topic on the cluster is transparent to the client code. There is no API difference between topics on a cluster member and topics on a client.
Other New Features and Enhancements in Coherence CE 25.03
COH-31826 Enhanced automatic detection of persistence targeting remote file-systems by identifying file system type osfc2 as a remote file-system and in such cases auto-enabled je.log.useODSYNC to ensure database integrity in such environments.

COH-31608 Updated OpenTelemetry to version 1.46.0.
COH-31596 Fixed an issue that could prevent OpenTelemetry spans from being properly linked.
COH-31497 Fixed an issue where taking snapshots without suspending the service could result in thread starvation due to concurrent requests.
COH-31480 Fixed an issue where RemoveCount on the StorageManager MBean was not being reset when calling resetStatistics().

COH-31325 Fixed an issue where the ContinuousQueryCache constructor did not honor the request for no local cache values when a map listener was provided. Note: this fix results in a behavior change as the CQC constructor now infers that the provided listener is a lite listener.
COH-31253 Fixed an issue where internal CacheStore operations can result in unsolicited commit events.
COH-31217 Fixed an issue where calling seek() on a topic subscriber could intermittently cause a ClassCastException on a subsequent receive() call.

COH-31092 Fixed the issue where SimilaritySearch aggregator couldn't be executed asynchronously.
COH-31022 Fixed an issue where persistence snapshots could produce a NullPointerException in some rare circumstances if a rolling upgrade to remove cache mappings was not correctly done.

COH-30969 Fixed an issue where InFilter queries could take longer to return.
COH-30950 Fix equality and hash code 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").
COH-30939 Fixed a thread safety issue when calling removeAll on SafeHashMap.
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.

COH-30426 Added the ability to reference property names of JSON data and Java Record in CohQL. Note that older .NET and C++ extend clients using QueryHelper need to be upgraded to work with this change.
COH-30132 Fixed an issue where a ClassCastException or NullPointerException may be thrown by InvocableMap during service config processing in some very rare scenarios.
COH-29982 Added backwards and forward compatibility support for system properties with prefix com.oracle.common and com.oracle.coherence.common, if system property lookup fails beginning with one prefix, retry lookup with alternative prefix. This change accommodates moving package com.oracle.common to com.oracle.coherence.common in Coherence version 14.1.1.0.
COH-29800 Fixed an issue where the backing map manager wasn't correctly set and initialized when using a View Scheme.
