A fix for this NPE was merged into
masterin #5012. The latest published 3.x release, 3.3.0, predates that merge and does not include the fix.Could you share the exact ServiceComb version you are using? If you can test a build from
masterin a development environment, please also confirm whether it resolves your reproducer. I have not found a backport PR to3.3.xor 2.x.
