[Insight-users] Java troubles

[Blezek, Daniel J (Research)]

Hi all,

  I've been wanting to use ITK inside Java for various reasons.  I did a
fresh checkout yesterday, and built with Java wrapping on.  I compiled the
cannyEdgeDetectionImageFilter.java class and ran.  The program promptly
seg-faulted inside the JNI wrappers (see log below).  I'm running RedHat
8.0, GCC 3.2 and Java 1.4.1_02.

  This bug was reported as #893
(http://www.vtk.org/Bug/bug.php?op=show&bugid=893&pos=8), has anyone made
any progress, or could give me some direction?

Thanks,
-dan
