[cp-patches] Fix for java_lang_VMProcess.c

[Archie Cobbs]

I've checked in the attached patch which fixes a core dump (in the
child process) when a zero length command array is passed.

       * native/jni/java-lang/java_lang_VMProcess.c: Fix segfault
       in the case that a zero length command array is passed.
