--------------------------------
Summary: Avoid ThreadLocal leakage etc at shutdown so that Broker
behaves better when embedded within Containers
Key: QPID-4271
URL: https://issues.apache.org/jira/browse/QPID-4271
Project: Qpid
Issue Type: Bug
Components: Java Broker
Reporter: Keith Wall
Fix For: 0.19
Some customers are embedding the Java Broker within application containers such
as Tomcat.
Successive undeploy/redeploy of the component shows warnings highlighting
potential ThreadLocal leaks on Container owned threads. For instance, Tomcat
reports:
{noformat}
SEVERE: The web application [/qpid-0.19] created a ThreadLocal with key of type
[org.apache.qpid.server.logging.actors.CurrentActor$1] (value
[org.apache.qpid.server.logging.actors.CurrentActor$1@661eef2c]) and a value of
type [java.util.Stack] (value [[]]) but failed to remove it when the web
application was stopped. Threads are going to be renewed over time to try and
avoid a probable memory leak.
SEVERE: The web application [/qpid-0.19] created a ThreadLocal with key of type
[org.apache.qpid.framing.AMQShortString$1] (value
[org.apache.qpid.framing.AMQShortString$1@7382ab3e]) and a value of type
[org.apache.qpid.framing.AMQShortString$1$1] (value [{queue=queue, ping=ping,
test-ping=test-ping, test-queue=test-queue}]) but failed to remove it when the
web application was stopped. Threads are going to be renewed over time to try
and avoid a probable memory leak.
