[jboss-jira] [JBoss JIRA] (WFLY-8882) Artemis client uses unbounded threap pool
Jeff Mesnil created WFLY-8882:
---------------------------------
Summary: Artemis client uses unbounded threap pool
Key: WFLY-8882
URL: https://issues.jboss.org/browse/WFLY-8882
Project: WildFly
Issue Type: Bug
Components: JMS
Affects Versions: 11.0.0.Alpha1
Reporter: Jeff Mesnil
Assignee: Jeff Mesnil
Priority: Critical
Artemis client thread pool can be configured using the messaging-activemq subsystem's
global-client-thread-pool-max-size attribute (introduced in 11.0.0.Alpha1).
By mistake, the default value of this attribute was set to -1 (through the
ActiveMQClient.DEFAULT_THREAD_POOL_MAX_SIZE constants).
This means that unless configured otherwise, the Artemis clients running in the app server
(e.g. MDB code) will use an unbounded thread pool.
The correct configuration is to *not* have a default value. If that's the case,
Artemis will determine the size of the pool depending on the number of processors (8 *
Runtime.getRuntime().availableProcessors())
