[hibernate-dev] GenericConstraintDef extends raw ConstraintDef

[Hardy Ferentschik]

Hi,

I recommend you create an issue on Jira -  
http://opensource.atlassian.com/projects/hibernate/browse/HV

Defining GenericConstraintDef as you suggest is of course correct. The  
reason for not using generics was
to avoid IDE warnings like "Unchecked call to 'constraintType(Class<A>)  
..."

I don't understand though why using the raw type should be not allowed. It  
might not be expected, but
I think it is correct.

I also don't understand why the problem is only occurring with Eclipse.  
Wouldn't eclipse use the same JDK
you are suing from the command line? Or do you have multiple JDKs  
installed?

I know there are issues compiling Validator using Open JDK -  
http://opensource.atlassian.com/projects/hibernate/browse/HV-318.
But that would imply that you are using two different JDKs.
