---------------------------------
Summary: Meta space memory leak caused by the shutdown hook of
ProcessManager
Key: BEAM-9006
URL: https://issues.apache.org/jira/browse/BEAM-9006
Project: Beam
Issue Type: Bug
Components: java-fn-execution
Reporter: sunjincheng
Assignee: sunjincheng
Fix For: 2.18.0
Currently the class `ProcessManager` will add a shutdown hook to stop all the
living processes before JVM exits. The shutdown hook will never be removed. If
this class is loaded by the user class loader, it will cause the user class
loader could not be garbage collected which causes meta space memory leak
eventually.
