After upgrading Jenkins from 1.x to 2.x
And After upgrading Cobertura-Plugin from 1.9.8 to 1.12.1

I'm no more able to use decimal number in Coverage Metric Targets

For instance, for line coverage targets, I set value 80, 55.29, 55.29.

In the config xml, I could see the following

<lineCoverageTargets>80, 55,29, 55,29</lineCoverageTargets> 

First time the job is running, values changed to : 80, 55, 29

I tried to put decimal using "," or "." but it doesn't change this behavior.
