We are currently using Flink's Local Env mode (executing Flink tasks within the local JVM). We are starting many "Flink query Iceberg tasks" sequentially within the lifecycle of a single JVM (which can be considered a long-running service). After the JVM runs for a while, we can observe a metaspace memory leak. By examining the leaking ClassLoaders, we found that Iceberg's ExecutorService is registered to the ShutdownHook (GC root).   I noticed that these ExecutorServices are actively shut down. Theoretically, they don't need to be registered to the ShutdownHook. -- This is an automated message from the Apache Git Service.
