It seems that the fix for "9-Debian" Java version does not work for "11-ea" like string:

It seems to be called from here via Gson().fromJson:

Ugh. We should just create a multi-release jar so that we can use Runtime.Version on 9+.

Hi, is there any way to work around the issue until a patch is available ?

Ok, Updating to 2.8.5 solved the issue for me.
