    at hospitalmanagement.Physician.<init>(Physician.groovy)

This is telling you that hospitalmanagement.Physician is trying to access a Patient property which doesn't exist (in the same class).

No idea how you should solve that since you haven't shown the corresponding code.

There is a solution at the link below. It worked for me. http://forum.springsource.org/showthread.php?120786-Upgraded-from-Grails-1-3-7-to-2-0-and-am-getting-method-lt-init-gt-%28%29V-not-found-error&p=409849#post409849
