Hello, Among the problems I found in the ordering of property sources[1], there is the question of the meaning of the numeric priority value:
* the manual says that lower numeric values override higher values[2], * the Javadoc suggests an inverted order[3]. Which one should be the correct one? At first I implemented the documentation order[4], since users might have learned that one (although this order never worked, the first JIRA issue reporting it is from last December). However this leaves a bitter aftertaste, because the provider's priority uses the "highest value wins" strategy. I rebased my PR [4] (taking LOG4J2-3413 into account in the tests) and I am planning to merge it in the weekend.
