org.infinispan.jcache.embedded.JCacheManager#create always throw CacheConfigurationException if create cache with template -------------------------------------------------------------------------------------------------------------------------- Key: ISPN-11918 URL: https://issues.redhat.com/browse/ISPN-11918 Project: Infinispan Issue Type: Bug Components: JCache Affects Versions: 10.1.8.Final Reporter: Sammy Chu Priority: Major Attachments: ISPN-11918-fail.log, ISPN-11918-success.log, ISPN-11918.zip Our project upgraded from Infinispan 8.2.4.Final to 9.4.18.Final and got `org.infinispan.commons.CacheConfigurationException: ISPN000453: Attempt to define configuration for cache MY_CACHE_NAME which already exists` . We are defining the cache template and then programmatically define the JCache with jcache configuration. From the source code of [JCacheManager|https://github.com/infinispan/infinispan/blob/master/jcache...], it is reading the `baseConfig` as the template and then merge it with the jcache configuration, which is working expected in 8.2.4.Final. Now upgraded to 9.4.18.Final, it is not working due to change of ISPN-7540. We checked this issue also reproducible on current latest stable release (10.1.8.Final). [^ISPN-11918.zip] is a simple standalone application to reproduce this issue, change infinispan version from 10.1.8.Final to 8.2.12.Final will work correctly. Attached the trace log [^ISPN-11918-fail.log] when stay on 10.1.8.Final and [^ISPN-11918-success.log] when changed to 8.2.12.Final.
