Jar files wrongly classified als deployable modules

When the library folder of an EAR (/lib) or WEB module (/WEB-INF/lib) contains jar files that have a Main-Class entry in their manifest file, Jboss tools designates them as "J2EE Application Client Module".

This is visible in the GUI in the Servers view when unfolding a runtime server. The above mentioned jar files from EAR/lib are listed between the normal EJB and WEB modules. When you unfold a WEB module in this view, the above mentioned jar files from /WEB-INF/lib are listed here.

The problem is also visible in the server log. For each jar file being present in EAR/lib and WEB-INF/lib with the mentioned Main-Class entry, a message is printed:

"Module [name of jar file] published without error."

Additionally, if a jar file in EAR/lib has classes with EJB annotations, a similar thing happens as with jar files that have a Main-Class entry. The only difference is that in this case the jar file in question is being branded as "J2EE EJB Module"
