According to information received from the original reporter, my above speculation is correct. Thus I am closing this as "not a bug".

Without a test case I can't be certain, but based on the reporter's description, this is likely a result of the fix for JDK-8089681. If so, then this is not a bug, but rather an intentional change in behavior. See JDK-8154127, where we documented this change.
