[Simple-support] Transform of class not supported

[Rafael A. <ang...@gm...>]

Hello everybody,

I have been using Simple Framework for some time now and I think is greate
and very easy to use. I'm working with simple inside a Eclipse plug-in
project.

However, I had to move the serializable classes to a different plug-in
project due to some requirements. The serializable classes are the same, but
I get this exception:

org.simpleframework.xml.transform.TransformException: Transform of class

I know maybe this problem goes beyond the scope of this list, but I have no
idea of what is wrong.

Thank you very much for your help.
