> 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/embedded/src/main/java/org/infinispan/jcache/embedded/JCacheManager.java#L170], 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).
