      Description

      We have noticed another deadlock with the group metadata lock with version 1.1.

      Found one Java-level deadlock:
      =============================
      "executor-Heartbeat":
      waiting for ownable synchronizer 0x00000005ce477080, (a java.util.concurrent.locks.ReentrantLock$NonfairSync),
      which is held by "kafka-request-handler-3"
      "kafka-request-handler-3":
      waiting for ownable synchronizer 0x00000005cbe7f698, (a java.util.concurrent.locks.ReentrantLock$NonfairSync),
      which is held by "kafka-request-handler-4"
      "kafka-request-handler-4":
