The documentation currently says
FORMAT_MESSAGES_PATTERN_DISABLE_LOOKUPS
is the correct environment variable to disable the message pattern lookups, however after testing, it seems thatLOG4J_FORMAT_MSG_NO_LOOKUPS
is actually correct. (It also fits in with the other environment variables)Even though this option is deprecated in the newest version, this could make people wrongfully think
FORMAT_MESSAGES_PATTERN_DISABLE_LOOKUPS
works on older deployments where the log4j version is not able to be updated.
