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

[Marco Sambin]

Hi all.
I have a couple of questions in this regard:

1 - Will VTK 6 work with Java 7 on Mac OS X? According to my experience,
Oracle's JVM (v7) works much better than Apple's one (v6), especially for
web deployments (Java Web Start / Java Applet).

2 - How "sensitive" is VTK to the version of the JRE it is linked against
vs the version the application is run with? It must absolutely be the SAME
EXACT version? Or there is some "tolerance"? The crucial point is the
version of the jawt library? Or what else? I ask this question because
especially with web deployments (e.g., Java Web Start) it is very difficult
to control which exact JRE version the client is running.

Thanks in advance for your comments.

Regards,

Marco
