java - Ljava.lang.String class cannot be resolved in persistence.xml -

I'm using JBoss Developer Studio I have a project with a firmness. The Xml file file is perfect for me, but I keep this error in my project list.

  class "[ljava.lang.String; @ 22ec7158" can not be solved]  

I include pictures for a better reference.

When I click on the error I am going to take me to the place where the error is happening, it takes me to the end of the file.

persistence.xml

You can solve it already, however, the cause of the problem in my case

Edit: The exact reason for this error message is that the error generator is trying to run a string () on the string array when it generates error messages.
