-----------------------------------
Summary: ThreadLocals in Layout implementations should be
non-static to prevent memory leaks in web containers
Key: LOG4J2-1142
URL: https://issues.apache.org/jira/browse/LOG4J2-1142
Project: Log4j 2
Issue Type: Improvement
Components: Layouts
Affects Versions: 2.4
Reporter: Remko Popma
Assignee: Remko Popma
Fix For: 2.4.1
As discussed in LOG4J2-1125, storing ThreadLocal<StringBuilder> in a static
field may not interact well with the thread pools and class loaders of some web
containers and may result in memory leaks, especially in older web containers.
