JolokiaCollector is not working

[Lilili2019]

Having trouble to get the JolokiaCollector to work. So first I followed the doc https://diamond.readthedocs.io/en/latest/Getting-Started/Configuration/ to setup the JolokiaCollector:
diamond-setup -C JolokiaCollector

But after restarted Diamond, the diamond.log shows some issue. Any thoughts why i am getting below ERROR?

Python2.6 support was dropped 11 months before this issue was created. If you still see this with master under 2.7, reopen and please include current collector config and logs.
