[vtk-developers] error: 'jvariant::jvariant(jbyte)' cannot be overloaded

[Mathieu Malaterre]

I was using:

sudo apt-get install openjdk-6-jdk ; export
JAVA_HOME=/usr/lib/jvm/java-1.5.0-gcj-4.3-1.5.0.0/

It looks like official debian package are actually using Eclipse Java
Compiler 0.894_R34x which does not exhibit this behavior.

So please discard issue for now.

Thanks
