Hi Mike,
yes, not so difficult.
I submitted a patch (#0967) providing doxygen docs
and cleaning up ClassHelper.

Please consider this patch first,
because this eases further work.
There are many bugs located in ClassHelper.

Confirmed, this looks like an oversight in the org.octave.ClassHelper class, should be an easy fix if you want to provide a patch.

Tue 02 Aug 2016 12:52:29 PM UTC, original submission:  

with the attached testclass on the classpath (javaaddpath),
it is no problem to set iVal but setting bVal results in an error:

octave:2> javaObject('eu.simuline.octave.OctaveInterfaceTester')

octave:3> java_set(tester,'iVal',-127)
octave:4> java_set(tester,'bVal',-127)
error: [java] java.lang.IllegalArgumentException: Can not set byte field eu.simuline.octave.OctaveInterfaceTester.bVal to null value
error: called from
    java_set at line 48 column 16


Comment: at the moment, the java interface is nearly UNUSABLE
in particular because of bug 48013.
But there are many further bugs I submitted.
I would be willing to provide bugfixes for all of them,
but still no enough input to do so.
The bugs refer all to a small number of files
and so I must do one after the other.

Please help me working on java integration.
