This issue is still present in Octave 4.2.0.

I found that arrayfun is unable to handle java arrays, instead I get a "can't perform indexing operations for octave_java type" although indexing with () works fine. How to reproduce:

octave-cli-3.8.1> js = javaObject ('java.lang.String', 'hello');
octave-cli-3.8.1> jsa = javaMethod ('split', js, '')
octave-cli-3.8.1> jsa(2)
ans = h
octave-cli-3.8.1> jsa(3)
ans = e
octave-cli-3.8.1> arrayfun (@char, jsa, 'UniformOutput', false)
error: can't perform indexing operations for octave_java type
