             Summary: Possible class leaks in flink-table / sql modules
                 Key: FLINK-25968
                 URL: https://issues.apache.org/jira/browse/FLINK-25968
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner, Table SQL / Runtime
    Affects Versions: 1.15.0
            Reporter: Yun Gao


This is the umbrella issues for possible class leaks in flink-table / sql 
planner and runtimes.

Currently for a flink cluster, the flink classes are loaded by the system 
ClassLoader while each job would have separate user ClassLoaders. In this case, 
if some class loaded by the system ClassLoader has static variables that 
reference the classes loaded by the user  ClassLoaders, the user ClassLoaders 
would not be able to be released, which might cause class leak in some way.
