Did you set the JAVA_HOME environment variable first?
In Octave:
setenv ("JAVA_HOME", "/full/path/to/Java/JDK")
such that <JAVA_HOME>/jre/bin/client (with some arch subdir setting
somewhere in between)
points to the jvm library?
On some 64-bit systems (which may include OSX) it should rather point to
<JAVA_HOME>/jre/bin/server (with arch in between somewhere)
or perhaps a symlink is needed in ./server to the jvm in ./client.
Have a look at the wiki (Java pkg section),
http://www.octave.org/wiki/index.php?title=Java_package
(still incomplete as to these specific gotchas :-( )

No, a bit higher up it says:
" java: Java Development Kit not found"
which usually means that JAVA_HOME wasn't set properly.

Yeah, you hit two of my favorite issues on the head:
- Java pkg silently installing only half way when a JDK isn't found by the
Java package install scripts.
I have some ideas on how to fix this (checking the JDK / JAVA_HOME setting
in preinstall.m), but no time now.
- Octave's pkg command not being able to roll back a failed package
installation.
Luckily, you can do a manual:
pkg uninstall java
from within Octave.

Yes, the Java development kit (JDK) not found message.
Anyway, I appreciate your experiments with the Java pkg on OSX.
