SEVERE: The web application  created a ThreadLocal with key of type [net.sf.jasperreports.engine.fonts.FontUtil$1] (value [net.sf.jasperreports.engine.fonts.FontUtil$1@2fdb83b8]) and a value of type [java.util.HashSet] (value []) but failed to remove it when the web application was stopped.

If I had the choice, I would NEVER use Jasper Server again. I would rather use groff, xslt or html2pdf, one of the numerous dedicated PDF libraries, or even a "backyard" solution written by a non-English speaking hermit with zero support.
