--- Begin Message ---Package: libjfreechart-java Version: 1.0.9-1 Severity: serious Hello, Unfortunately, unlike what is said in the changelog, libjfreechart-java does not work with free JVM available. As I proof, I joined a test case, TestJFreeChart.java. I compiled it with gcj: /usr/lib/jvm/java-gcj/bin/javac -classpath /usr/share/java/jfreechart.jar:/usr/share/java/jcommon.jar TestJFreeChart.java I run it with different runtimes using commands in the spirit of: /usr/lib/jvm/java-1.5.0-sun/bin/java -classpath /usr/share/java/jcommon.jar:/usr/share/java/jfreechart.jar:. TestJFreeChart The runtimes never complain about anything going wrong. Unfortunately, when I look at the test.png files produced with free runtimes (cacao, gcj-compat, kaffe), the PNG files are empty, while they do display nice charts for the two runs with sun's jre. It seems libjfreechart-java will probably have to go back to contrib, as this bug is rather serious - if not grave (it simply cannot run properly in main). Sorry to bring bad news...

It just refuses to work on my machines... Could it be a weird interaction with sun's java ? Cheers, Vincent, closing this bug...
