All jars should have a Automatic-Module-Name entry added to the MANIFEST.
Unfortunately this is currently not doable because we have split packages, which are forbidden by the Java module system.
The big offenders are some packages which are present in infinispan-commons:

• org.infinispan.configuration.cache for the single XSiteStateTransferMode class
• org.infinispan.counter
• org.infinispan.lock
• org.infinispan.multimap
