Hi Thorsten, Could you please create a JIRA issue for this problem? -- Ceki On 18.02.2019 16:08, Thorsten Heit wrote:
Hi,
I just joined this list, so first hi from Germany ;-)
When I use slf4j-1.8.0-beta2 in an application that is being deployed to our Websphere 9 server, I see error messages in the deployment manager console:
(...) [2/18/19 15:51:31:862 CET] 000022bd WSModuleDescr E WSWS7011E: The configuration for the myapp-war-2019.4.0-SNAPSHOT.war application module cannot load correctly.

Switching back to the older 1.7.25 version lets this error message disappear.
The reason is that Websphere uses Java 8 which cannot parse / process the module-info.class that was compiled with Java 9.
Solution for these kinds of problems: Move the class to META-INF/versions/9 and mark the resulting Jar as a multi-release. See [1] for how to do this.
What do you think? I can create a pull request on Github if you like.
Regards
Thorsten
