[JENKINS-7772] Some characters in data cause build breaks, loss of function

When adding values to an axis variable, if a comma "," is included in a value, the build succeeds, but you cannot "click through" to see the details about that particular combination.

If a pipe "|" is in a value, then the entire matrix build shows as a failure, though it appears the jobs are all launched.

Raw content of original issue

When adding values to an axis variable, if a comma "," is included in a value, the build succeeds, but you cannot "click through" to see the details about that particular combination.


If a pipe "|" is in a value, then the entire matrix build shows as a failure, though it appears the jobs are all launched.

No source files or tests are named. Start by tracing how matrix axis values containing commas and pipes are handled, then reproduce both reported behaviors; done means the build remains successful and the affected combination remains clickable.
