Red Hat Issue Tracker RESTEASY-841 Major Closed No error is thrown if the same class is present in both Application.getClasses() and Application.getSingletons() 2016-08-02 16:15:29 UTC

Description Pavel Macik 2013-03-13 09:59:52 UTC
To reproduce the issue use following steps:
1.) Get the reproducer from git://github.com/pmacik/jaxrs-cdi-reproducer.git
2.) Get out-of-the-box JBoss AS7 (7.1.1.Final)
3.) Start the AS up
4.) Build the reproducer WAR using "mvn package"
5.) Deploy the reproducer WAR - copy the WAR into (JBOSS_HOME)/standalone/deployments directory
6.) Go to http://localhost:8080/JAXRS-CDI-reproducer/rest/bean/getAll -> NPE is thrown (bean was not injected)
7.) Go to http://localhost:8080/JAXRS-CDI-reproducer/BeanServlet -> the bean is properly injected

There is a workaround - deploy WAR before AS start-up.

Comment 1 Stuart Douglas 2013-03-16 04:26:38 UTC
Hot deployment does not actually have anything to do with it. It appears to be a race condition in deployment, sometimes it works and sometimes it does not.

Comment 2 Stuart Douglas 2013-03-16 05:13:23 UTC
This is actually caused by user error. In the reproducer the class should only be returned by Application.getClasses(), not Application.getSingletons(). 

Ideally RESTeasy would detect this case, and would throw an error. I have filed an issue against RESTeasy to detect this problem.
