Github user twogee commented on the issue: https://github.com/apache/ant/pull/50 SLF4J was written by the [author of Log4j](https://en.wikipedia.org/wiki/Log4j) who wrote [an article](https://articles.qos.ch/classloader.html) cataloguing the problems with Commons Logging. When upgrading Jasper, one gets various versions of commons-logging as dependencies; the latest versions depend on slf4j-nop in runtime, though ð Log4j is EOL and the latest versions add dependencies on J2EE (see the removed comment in libraries.properties ;-)
