Oops, sorry about this - In #726 I committed the regular Java jsonutil as well as the android-java jsonutil. This was unintentional, as PR #726 was only meant to change the android-java stack.

+1 to this PR being merged.

I was able to repeat the issue with the develop_2.0 branch and this PR resolves the issue.
