REF: JDK-8235446: confusing error message for records with no parens

[Maurizio Cimadamore]

Hi,
few comments:

* is the call to checkSourceLevel needed? After all you already check 
for enable-preview

* I think the error message should just be:

"record components expected"

(and perhaps we should move the position of the error message to _after_ 
the record keyword).
