rotating pattern: /usr/local/tomcat8/logs/catalina.out forced from command line (5000 rotations)

olddir is /var/log/tomcat/oldlog, empty log files are not rotated, old logs are removed

considering log /usr/local/tomcat8/logs/catalina.out

 log needs rotating

rotating log /usr/local/tomcat8/logs/catalina.out, log->rotateCount is 5000
