I’m doing a fairly “by the book” clobber update (store and fetch below work
fine) on an entity using the Java client. I’m seeing an error that happens at
type-inference time within the Riak Java client. I’m pasting below the exact
test that I’m using to generate this, as well as the stacktrace. Please let me
know if I’m missing something or if it’s a known bug.
Thank you
Cosmin
