The rule hibernate4-00038 doesn't catch classes inheriting from org.hibernate.type.descriptor.java.{javatype}

The rule hibernate4-00038 doesn't catch a class that inherits e.g. from org.hibernate.type.descriptor.java.AbstractTypeDescriptor even though AbstractTypeDescriptor is clearly present in <where param="javatype"/>.

This seems to be caused by the whitespace inside <matches pattern="..."/>. When I remove the whitespace, the problem is gone.
