Fails to load plugin with the following error:

Which version of Graylog you are using? Which version of plugin you are using? Compiled by yourself or using one from releases page?

kurrier commented 6 years ago

Graylog 2.3.2 and 2.4.0 Plugin version 2.3.1 and 2.1.1b - Tried jar release and self compiled, same results all around.

kurrier commented 6 years ago

Adjusted settings pom.xml `2.3.1</graylog2.version>

0.9.55` To: `2.4.0 0.9.60` Then loading [syslog4j-0.9.60](https://github.com/graylog-labs/syslog4j-graylog2/releases) directly into java classpath resolved the issue

Sorry for delay. Strange what you needed to add syslog4j-0.9.60 JAR into classpath. As far as I can see, graylog 2.4.0 JAR (one in docker) includes syslog4j....
