Strange stacktrace discovering font ressources

Hello,

We are using JasperReports 3.7.6 and are experiencing a strange problem when trying to generate reports from our Tomcat 6 production server. The problem appears when we undeploy the web application and upload a new version. If we stop the container and then restart, the problem disappears.

If the report relies on any fonts that are in the ressource file, the generation fails. If not, the stacktrace still appears in the log, but the report is generated anyway.

See the complete Stacktrace below, with debugging information from JasperReports.

Thanks for your help : let me know if I should post this in the tracker ...

Best regards,

Raphael Neve
