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

Mon May 13 17:23:05 EDT 2013

Hi Marco,

you got it right and unfortunately VTK 6.0 won't have Java 7 support on OS
X.
This might happen later on, but it will certainly not happen when VTK 6.0
get's out, specially as it is not a trivial fix.

But if you want that to be done sooner, you can either contribute it or
fund us to fix it.
