It works in Lucid Lynx beta 1 !!!

I tried to reproduce this bug today using iReport 3.7.1 and openJDK-6,
everything works as spected: load a jrxml file, preview with data from
postgres and sent to a Laser printer. Printed output was fine.

java -version ouput:
java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18~pre4-1ubuntu1)
OpenJDK 64-Bit Server VM (build 16.0-b13, mixed mode)

** Changed in: openjdk-6 (Ubuntu)
       Status: Incomplete => Invalid

Bug description:
All reports created using jasper reports (http://jasperforge.org/plugins/project/project_home.php?group_id=102) are outputted blank with the OpenJDK included in Intrepid and Jaunty. I'm seeing this on different machines, so I guess it's not a local configuration problem.

This is a critical bug since some commercial-strength software, expecially on the server side, are relying on JasperReports to do their Business Intelligence analysis. At my company, we lost several days after an Intrepid upgrade hunting down this (we initially blamed JasperReports, or a bug in the application generating the data). They heavily pressured me to switch to Windows 2003 Server due to this :-(.

To try out this bug, download iReport from http://jasperforge.org/plugins/project/project_home.php?group_id=83, unpack it, create an empty report, and try generating an output with an empty dataset (or set up one) -- it doesn't matter the output format.

No text will be displayed, even for static labels.

Maybe I'm wrong, but if I recall correctly it worked with Hardy's OpenJDK.

Switching to Sun's official (non-free!) JDK 6 fixes this, anyway.
