Joshua Popoff commented on LOG4J2-2241: --------------------------------------- Yes, this is running with Java 9. A module-info that contains a "provides" would also be necessary for it to work as intended, as far as I can see. I'm find with a second JAR just for Java 9, though it is a bit on the hacky side. > log4j-slf4j-impl does not provide slf4j with the service provider with Java 9 > ----------------------------------------------------------------------------- > > Key: LOG4J2-2241 > URL: https://issues.apache.org/jira/browse/LOG4J2-2241 > Project: Log4j 2 > Issue Type: Bug > Components: SLF4J Bridge > Affects Versions: 2.10.0 > Reporter: Joshua Popoff > Priority: Blocker > > log4j-slf4j-impl does not > {noformat} > provides org.slf4j.spi.SLF4JServiceProvider with > org.apache.logging.slf4j.SLF4JServiceProvider;{noformat} > (due to no module-info.java, and only an automatic module name, in the > log4j-slf4j-impl project. > When ran: > {noformat} > SLF4J: No SLF4J providers were found. > SLF4J: Defaulting to no-operation (NOP) logger implementation > SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details. > SLF4J: Class path contains SLF4J bindings targeting slf4j-api versions prior > to 1.8. > SLF4J: Ignoring binding found at > [jar:file://[redacted]/log4j-slf4j-impl-2.10.0.jar!/org/slf4j/impl/StaticLoggerBinder.class] > SLF4J: See http://www.slf4j.org/codes.html#ignoredBindings for an explanation. > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
