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...
Vincent
PS: I unfortunately don't have a single idea about what is causing
this problem.

I cannot reproduce the bug anymore either. So I think it was fixed by
some gcj-4.3 upload.
