[cdi-dev] [JBoss JIRA] (CDI-710) Require default event ExecutorService to be managed on Java EE

[John Ament (JIRA)]

    [ https://issues.jboss.org/browse/CDI-710?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448378#comment-13448378 ] 

John Ament commented on CDI-710:
--------------------------------

As the reporter notes, its to mandate that you're using the ManagedExecutor provided by the container if none is specified by the caller.  Right now in OWB, they're relying on ForkJoinPool.commonPool() to do the work, which is an odd default choice.  Weld has a property I believe which makes sense, and of course in OWB you can override it via properties if you need to.

> When running on a Java EE environment, CDI should use a managed executor service by default for asynchronous operations.
> This is already required by the JAX-RS 2.1 spec (http://download.oracle.com/otndocs/jcp/jaxrs-2_1-pfd-spec/index.html), section 5.8:
> {quote}In an environment that supports the Concurrency Utilities for Java EE [13], such as the Java EE Full Profile, implementations MUST use ManagedExecutorService and ManagedScheduledExecutorService, respectively. The reader is referred to the Javadoc of ClientBuilder for more information about executor services.{quote}
> Containers will presumably offer monitoring features and thread pool configuration options for managed executor services.
