Thank you Jörg.
I tried the two solutions, but unfortunately didn't work
I am doing some tests to see how annotation processing will be handled when
the "CustomerDTO" is within the same bundle. The surprise is it succeeded
only when I use :
stream = new XStream();
stream.processAnnotations(CustomerDTO.class);
It always failed when I set autodetectAnnotations to true (and remove
"processAnnotations(...)") even when I change Xstream's ClassLoader...
However I couldn't find a solution when I put CustomerDTO in a separated
bundle
