To take the same line as Sanne and Emmanuel, I don't think that these screenshot in itself are very helpful yet. It would be important to understand the footprint better and
follow the references to see what exactly is going on.

Maybe. The symptoms look similar.It would be useful to get more information about the application in general, e.g. what type (ear/war), number of persistence units, etc
Also is this screenshot taken right after startup? Or after some load was created? To test the Validator theory you can try to replace the Hibernate Validator version 
in the modules/org/hibernate/validator/main of your AS installation with the latest 4.3 release - 4.3.0.Final https://repository.jboss.org/nexus/index.html#nexus-search;quick~hibernate-validator
