https://github.com/apache/logging-log4j2/pull/198
@garydgregory Having the same "Provider
org.apache.logging.log4j.util.EnvironmentPropertySource not a subtype" problem
when loading the log4j libraries on two different class loaders, from what I
tested this fix seems to also fix my problem.
Could you give me an estimate as to when this fix will be incorporated in a
released version (I'm assuming log4j-2.11.2)?---
