> Key: FLINK-16245
> URL: https://issues.apache.org/jira/browse/FLINK-16245
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Task
> Reporter: Stephan Ewen
> Priority: Critical
> Labels: usability
> Fix For: 1.11.0
>
>
> As reported in FLINK-11205, a reference to the user-code ClassLoader can be
> held by some libraries, causing class leaks.
> One way to circumvent this class leak is if the ClassLoader that we set as
> the user-code ClassLoader is a delegating ClassLoader to the real class
> loader, and when closing the user code ClassLoader we null out the reference.
