It seems that if the values of an axis in a matrix project contains a comma, jenkins starts failing to execute the job.

I have only one axis

that contains the values:
postgresql,build-flex
mysql,build-flex
oracle,build-flex

the command of my maven project is : mvn clean install -P ${mvnProfile}

It works fine when there is only one profile but fails silently with a list separated with comma. I don't have logs to attach as it just says: Job xxxx return with FAILURE). Also note that I have a 404 when I click to view the 'sub job' execution details.

I have tried to quote, escape, urlencode the comma but it does not solve the issue.

My understanding of the bug is that the comma is also the separator of axis in jenkins. When we have multiple axis, in the URL, we can see they are comma separated: /myjob/.../axis1=value,axis2=value

I suspect jenkins is interpreting the comma in my parameter value as an axis separator and starts failing.

To be continued...
