Details:

This was working fine in octave 3.8.2, but produces an error in octave 4.0.0.
Tested on Linux with self-compiled executable and also on windows using the
official binaries.

Steps to reproduce:

runtime = javaMethod('getRuntime','java.lang.Runtime');
process = runtime.exec({'echo','x'})

expected result:
process = 
<Java object: java.lang.ProcessImpl>

actual result:
error: [java] java.lang.NullPointerException

The octave error is triggered in libinterp/octave-value/ov-java.cc line 715,
where a java exception in the parameter conversion code is detected and
reported.
