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

[Simeon Fitch]

Seb,

Thanks so much for your help and giving it a try.  Very much appreciated.

When it comes to Java 6 I think you've identified a significant part of the
problem. I learned that to ensure consistent use of Java 6 throughout the
build->execution cycle it is critical that JAVA_HOME be set to
"/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home" *before*
calling cmake. Otherwise it uses what /usr/libexec/java_home returns.

Once I set that and fixed a bug where  I was using vtkPolyDataMapper when I
should have been using vtkDataSetMapper (which also causes a crash) I was
able to get a simple test to run.

Getting Java 7 working is still an issue for us, but one I can defer for a
week or two. That said, know that I'm interested in helping out if others
have already started tackling the VTK + Java 7 on MacOS X issues, including
the port to use CALayer instead of NSView (as discussed here:
http://www.vtk.org/pipermail/vtkusers/2012-November/126603.html). I just
don't know enough of the landscape yet to be able to take that on by myself.

Cheers,

Simeon
