Because livereload tools use Require-Bundle instead of Import-Package to depend on slf4j.api, this project cannot use the rhel implementation (rh-common-java rpm) version of slf4j.api 1.7.4 .jar when installed via rpm on rhel/fedora.

Here's the line that is causing the problem:

https://github.com/jbosstools/jbosstools-livereload/blob/44af911aba916f0e4352a3c6a7961986bbb7d1db/tests/org.jboss.tools.livereload.test/META-INF/MANIFEST.MF#L36

We need to switch to using Import-Package to that any implementation of this package, regardless of Bundle-SymbolicName, can be used.
