[GitHub] flink issue #2065: [FLINK-4011] Keep UserCodeClassLoader in archived Executi...

    You already outlined one of the drawbacks (holding on to the classes).
    There are probably other parts in the execution graph that currently hold onto user defined classes as well.
    
    A good (but more involved) longer term solution would be to create a "archived execution graph" that can be serialized and that does not contain any user classes, but only "stringified" versions of configs, accumulators, metrics, etc.
