The original syslog4j dependency used, has been produced in 2010. There are no newer versions available and the project seems to be unmaintained. The main problem is that the original dependency contains Java 5 specific bytecode, which has been deprecated. More specifically, a project that I am currently working has been dealing with a problem similar to the one discussed here, where the culprit is the syslog4j dependency pull from here.
The solution appears to be to use the newer fork of the syslog4j library, from graylog2, which is mostly a drop-in replacement (it uses different package names).
