[arquillian-issues] [JBoss JIRA] Commented: (ARQ-335) Weld SE container does not properly load extension classes at boot

[Gunnar Morling (JIRA)]

    [ https://issues.jboss.org/browse/ARQ-335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12591991#comment-12591991 ] 

Gunnar Morling commented on ARQ-335:
------------------------------------

This seems to be a duplicate of ARQ-275, which was fixed with 1.0.0.Alpha5. I therefore think this issue can be closed.
