Jenkins Hangs While Submitting Changes In Manage Jenkins->Configure System

Issue

Your Jenkins instance hangs when saving changes made in Mangage Jenkins->Configure System.

Environment

CloudBees Jenkins Enterprise

Slave Setup Plugin

Resolution

Enabling deploy on save now in the Slave Setups section in Manage Jenkins->Confifure System causes the hang to
occur.

If you need this feature of the Slave Setup Plugin the hang will occur, but it does eventually complete.
Generating a Support Bundle while the hang is occurring and reviewing the thread-dump.txt file in the
nodes/master directory will show a thread with stack trace similar to:
