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.

  Hello again,

  I'm pretty much puzzled, as it actually works fine in a clean amd64
sid chroot. It just refuses to work on my machines... Could it be a
weird interaction with sun's java ?

  Cheers,

        Vincent, closing this bug...
