I have exactly the same problem. So, as per your example, suppose that we
change line 83 to
Object probablyTreeSiteManager =
selector.select(publication.getSiteManagerHint());
then
probablyTreeSiteManager.toString() prints
[EMAIL PROTECTED] which looks like it's
what we want. However, probablyTreeSiteManager instanceof TreeSiteManager
gives false and probablyTreeSiteManager.getClass().getName() prints
$Proxy193. However, probablyTreeSiteManager.getClass().getPackage().getName()
throws an NPE, so the package is null!
This reminds me of Hibernate proxies but other than that i have no clue of
what is going on. Anyone with a better idea?
