---------------------------------
Summary: Memory leak when doing deploy/undeploy app using REST and JPA
Key: WFLY-7037
URL:
https://issues.jboss.org/browse/WFLY-7037
Project: WildFly
Issue Type: Bug
Components: REST, XML Frameworks
Affects Versions: 10.1.0.Final
Reporter: Tomas Remes
Assignee: Stuart Douglas
Priority: Critical
Attachments: gc_path.png, mem-leak.zip
It seems that exposing some type (ApplicationUser in attached app) which has enum type as
attribute via REST api could cause memory leak (See steps to reproduce). You can observe
that person.joey.test.UserType instances are kept in memory when GC happens (metaspace
exceeds) and the path to GC root looks:
!gc_path.png|thumbnail!
Note that this map

was not available in 2.5.4 version used in WF 10.0.0.Final
