Hmm...here's what I get from the default OS X build:

$ otool -L /sw/lib/octave/3.8.1/liboctinterp.2.dylib
/sw/lib/octave/3.8.1/liboctinterp.2.dylib:
	/sw/lib/octave/3.8.1/liboctinterp.2.dylib (compatibility version 3.0.0, 
current version 3.0.0)
	/System/Library/Frameworks/JavaVM.framework/Versions/A/JavaVM 
(compatibility version 1.0.0, current version 1.0.0)
...

The JavaVM library is in a stable location with a hardcoded path, but 
I'm uneasy about the linkage now.

If, instead, the build is tweaked (requiring a patch) to use an Oracle 
JDK, then there's a runtime failure since libjvm.dylib reports its 
install_name as @rpath/libjvm.dylib.
