----------------------------------------

             Summary: Extend PluginLoader to allow closing of backing ClassLoader
                 Key: FLINK-23029
                 URL: https://issues.apache.org/jira/browse/FLINK-23029
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.14.0


The PluginLoader is currently never closing the backing classloader, which means that plugins remain loaded until the application shuts down.

This for example makes it impossible to use the plugins in the mini cluster, because they would be loaded multiple times.
