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

[Jeff Baumes]

My guess is that jboolean and jbyte are typedef'd to the same type on your
system. What version of Java are you using? Can you search for the typedefs
in jni.h (or other dependent header) to verify this?
I have compiled with Java wrapping with no problem on Ubuntu with gcc 4.3.3
and Java 1.6.0_13.
