Because I first put it myself in the cache. The data map already present in the cache node (I checked with peek) has all the information I need, plus the jboss:internal:uninitialized key which I don't need. When the cache finds that key, it decides to load data from the cacheloader. Well, I am calling getChildren() on a node, then getData() on the resulting map's values. Again, I get the data I want with that extra key added. Am I doing it the wrong way? Well, when I put data in the cache, I use the cache object. When I get data (in the first case, without involving children), I use get(Fqn) on the cache object then getData() on the node; I haven't found a better way to get all the node's data. I found that if I manually remove the uninitialized key immediately after putting a node in the cache, all the problems seem to disappear. However, this looks like an UGLY thing to do.
