Just edit the file in XML mode instead of Design mode and you can add
what you'd like. If you don't know what you want to enter, click Add
in design mode and add a new PU -- the JTA option may be available.
Then remove the original one -- that workaround worked for me.

I've filed a bug in NB about this already: https://netbeans.org/bugzilla/show_bug.cgi?id=178443

Cheers,
