Hi [~denes], Thanks for your reply. I am so sorry about missing the unit test.
Patch [^flume-2786-v1.6.0.patch.1] contains both fixing and unit test code.
As well, I uploaded a patch [^flume-2786-v1.6.0.test.patch] that only contains unit test code. Test wont be passed when apply [^flume-2786-v1.6.0.test.patch] to release-1.6.0.
