Roberto Carta commented on SOLDER-222:
--------------------------------------
I've find another way trying to solve my problem. This solution tries to use
two different class loader. First using original code, and if no
classes/resources are founded, using the _expectedType.getClassLoader()_.
Here the patch:

*But keep in mind that*:
- i'm not able to evaluate possibile side effects, as this class is havily used.
- i've written the minimum changes to this class, without altering other
classes, but you can try to locate a class twice with the same class loader,
depending on how methods/constructor are invoked.
In the hope it will be useful
