I presume that SLF4J merely passes these along to a supported framework, which must include at least these levels, and it is up to the framework to dictate the relative ordering? Or do you assume that all frameworks treat ERROR > WARN > INFO > DEBUG > TRACE ? Either way, it would be helpful to include at least one sentence stating this, or referring to the FAQ where the issue can be mentioned, similar to https://www.slf4j.org/faq.html#trace -- This message was sent by Atlassian JIRA (v7.3.1#73012)
