[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-825) hbm2java: Circular dependency between POJO source generation and Comparator class compilation

Max Rydahl Andersen commented on HBX-825:
-----------------------------------------

should definitly be work-aroundable with <meta attribute="property-type">thetypeyouwant</meta>

Remember to usa a recent version of hibernate tools.

A possible future "solution" is that getJavaTypeName detects that exception and mutates the comparater value to something guaranteed to work just when it needs to get the type.

> Hi,
> My java objects are generated from the xml files using hbm2java. One of my collection is sorted using a Comparator class. 
> hbm2java fails saying the comparator cannot be instantiated. But as the comparator makes reference to my java object, it cannot be compiled before the generation happened. We have  a circular dependency here.  (see example enclosed).
> Is there any way to fix this ? 
> Many thanks !
