Description

WeakReferenceMap.create(K key) logs once at warning level if a reference to a key was lost during creation.

referenceLostDuringCreation.warn("reference to %s lost during creation", key);

but it uses %s as the insertion point for the key, when it should be {}.

this means the log, if it ever surfaces, won't include the key.

i don't think this is a very important issue, but it exists.
