Error creating cloud watch appender with version 1.8.2-JAVA9MODULE_SLF4J17 and 1.8.1-JAVA9MODULE_SLF4J17

[rackdon]

I obtain an error when trying to initialize the cloud watch appender with version 1.8.2-JAVA9MODULE_SLF4J17 or 1.8.1-JAVA9MODULE_SLF4J17. It works fine with 1.8.0-JAVA9MODULE_SLF4J17 version. The error obtained is

@rackdon Thank you for the report! It's been fixed on version 1.8.3.

@rackdon Reproduced the error when I remove the line from module-info.java in an app. Do you have the line?

requires transitive org.slf4j;

[rackdon]

no sorry, why should I have that line?. My project is also in kotlin
