Description
Switching from the eclipse compiler to oracle or vice versa leads to a failure when unmarshaling a non-static object. The compilers generate different indexes for the this$N fields which causes a field not found exception.
I've attached a patch with a testcase which illustrates the problem and a stab at fixing it. The solution is to always put "defined-in" attribute for the this$N fields and at unmarshaling time completely ignore the name of the field in XML and find it by looking at the class fields.

The change in the v-1.4.x branch will break compatibility with previous patch versions. I guess that's fine but wanted to point it out anyway.
Thanks for the quick fix.

Thanks for the quick fix. What do you mean? There's no incompatibility with older versions. The version in trunk can still read the old format, but will write in a new one.

Thanks for the interesting example. I took a little different approach in the mapper only, based on the fact that the declaration sequence of the fields will be the same independent of the used compiler.
