Thanks for the updates and sorry for messing up the jira issue

Why should it load it when I put? It doesn't even do that currently.

I didn't put(node, key, value), but put(fqn, map). And it didn't load it from the cacheloader, until I tried to "get" something. I guess it did that because it thinks it should merge the map I gave it with the existing data. I need a way to tell it "just put this data and don't load anything". It should also not write that data to the cacheloader (this is yet another issue, I used a workaround for that too). The ultimate goal is to do my own optimized preloading of data from a database.

I wonder if the way to solve it is to have another "special" method like putForExternalRead. Anyway, as I said, my program works now with a cache listener and no cache loader. That will only run into problems if not all the data is present in the cache all the time.
