> @yuqi1129: Caffeine suggests using Java9 system scheduler if possible. [Wiki: Cleanup (ben-manes/caffeine)](https://github.com/ben-manes/caffeine/wiki/Cleanup) > > Would it work for you, or the specific classpath handling you are using, would cause issues with it? Unfortunately, we plan to support Java8 , what's more, the `Cache` instance is internal field of `CachedClientPool`, I'm afraid we can't change it except for the reflection mechanism. Let me explain our user cases. The Gravitino supports creating multiple catalogs, for example, assuming we have created 3 Iceberg catalogs ,each Iceberg catalog will use a separate classloader to load iceberg-related jars (include `iceberg-hive-metastore.jar`) to provide service. After some time, we do not need a specific catalog and we plan to drop it. When we plan to close the corresponding classloader, it cannot be GC by the JVM as there is still a daemon thread mentioned before in the issue, so we need a mechanism to explicitly close the daemon thread. can you give me some advice, thanks. -- This is an automated message from the Apache Git Service.
