Thank you for the reply.
I now have the following questions:
1) I cannot find this plugin deployed in the maven2 java.net repo.
Do i have to check it out, build and deploy it in a private repo?
2) In order to use the plugin for cyclic documents, do i have to:
a) implement my CopyBuilder which in its copy(Object) method does
ref accounting before invoking the super.copy(Object)
and also,
b) ensure that all xjc generated classes implement the Cloneable
interface (how?)
Is that correct?
3) (assuming the above assumptions are correct)
In the old 'extendedCloneable' plugin, you didn't use ref-accounting
at all, but instead ensured that all xjc-generated classes implement a
specific interface that handles cycles appropriately.
You have pointed out that using ref accounting with ThreadLocal does
not constitute a solid solution.
Do you think that ref accounting *within* copyBuilder is a safe operation?
4) Also, i couldn't find any mention of this plugin on jaxb2-commons site.
