[jira] [Created] (FLINK-32265) Use default classloader in jobmanager when there are no user jars for job

Fang Yong created FLINK-32265:
---------------------------------

             Summary: Use default classloader in jobmanager when there are no user jars for job
                 Key: FLINK-32265
                 URL: https://issues.apache.org/jira/browse/FLINK-32265
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.18.0
            Reporter: Fang Yong


Currently job manager will create a new class loader for each flink job even it has no user jars, which may cause metaspace increasing. Flink can use system classloader for the jobs without jars.
