[udumanajmeer]

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. Threads are going to be renewed over time to try and avoid a probable memory leak.

Try upgrading to the most recent version which now is 5.6.1. I think there was a memory leak bug in 5.2 that was fixed in the recent version. Unfortunately, Tibco Jaspersoft doesn't provide patches for the memory leak problem.

Like most other issues on the JasperSoft website, this issue is nearing ***SIX (6) YEARS** old and not resolved.

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.
