Resolution

You can workaround the issue by adding the dependency on "org.jboss.as.naming" to the module "org.jboss.as.weld.transactions". It is suggested to make a copy of the module in the root of {JBOSS_HOME}/modules, for example:

$ cp -R modules/system/layers/base/org/jboss/as/weld/transactions modules/org/jboss/as/weld/transaction

Then edit modules/org/jboss/as/weld/transaction/main/module.xml

        <module name="org.jboss.as.ee"/>
+       <module name="org.jboss.as.naming"/>
        <module name="org.jboss.as.security"/>

Once the issue is corrected, remove the module copy, but until then, patches won't overwrite the change.

An issue report has been filed: Content from issues.jboss.org is not included.JBEAP-18033.

Root Cause

This is caused by a missing dependency on "org.jboss.as.naming" in the "org.jboss.as.weld.transactions" module. Specifically JTSSynchronizationWrapper imports NamespaceContextSelector.
