Yes, this made the "new and noteworthy" for 2.1: 
http://eclipse.org/webtools/releases/3.1.0/newandnoteworthy/jpa.php

It's because it isn't set up to *provide* libraries for the JPA facet. 
Note that if you use "Disable library configuration", you should be in 
the same boat as 2.0.x, only with a configuration warning.

Unfortunately, WTP server runtimes do not yet provide this functionality.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=254536
https://bugs.eclipse.org/bugs/show_bug.cgi?id=254537
https://bugs.eclipse.org/bugs/show_bug.cgi?id=254540

For examples, you'll have to check JBoss Tools or OEPE, who I believe 
already have this funtionality, and unfortunately, for more help, WTP 
common would be a better place to seek it.

Hope this helps,
