[vtkusers] Is VTK 5.10.1 compatible with MacOS 10.8.3 and Java?

[Sebastien Jourdain]

Hi Simeon,

I've just tried your code and everything worked as expected, no crash on my
end.
=> OS X 10.8.3
=> Java 1.6.0_45

I suspect your VTK build may link to a different version of Java than the
one you run your application with.
