Details:

I have a Java class that accepts Octave function handles (OctaveReferences)
for performing callbacks.  The class loads without issue but is unable to call
doInvoke() to execute the callback functions.  The following error appears
verbatim on the Octave console.

error: [java] java.lang.UnsatisfiedLinkError:
org.octave.Octave.doInvoke(I[Ljava/lang/Object;)V

This was issue was originally noted on the help-octave list in June 2014, with
Octave 3.8:
https://lists.gnu.org/archive/html/help-octave/2014-06/msg00061.html
The post suggests that Octave 3.6 does not have this issue.

The attached Java class reproduces the problem.  Call it with:

x = javaObject('foo')
x.callBack(@(x) (disp(x)) )

I have reproduced the problem using the pre-built Win32 package as well as the
OS X package built using Homebrew.

I did search several different ways to see if this was submitted previously
and did not find any matches.  I apologize if this is a duplicate.
