Can you please attach the new Image.java file so I can compare between the two and
understand what I did wrong?
Thank you,

Description:
Hi,
This is the first time I've tried using XDoclet with Hibernate and its spewing out
some sort of error when I use it which leads me to believe the Hibernate plugin has a
bug.
I will attach the source-code I am running XDoclet against. Here is the exception I
get when I run XDoclet against it:
com.shadowcraft.desktopbeautifier.Image

Aparently caused by XMethod.getReturnType().getType() returning null which the
hibernate plugin does not expect or handle. I've filed a bug against XJavadoc against
this issue. See http://opensource.atlassian.com/projects/xdoclet/browse/XJD-44
