Parsing string arrays in org.apache.karaf.management.cfg doesn't ignore spaces

I can define "string array" properties in org.apache.karaf.management.cfg (e.g. enabledProtocols)

If I define enabledProtocols=TLSv1.2,TLSv1.1 everything is right. (Parsed values are "TLSv1.2" and "TLSv1.1")
But when I define enabledProtocols=TLSv1.2, TLSv1.1, array is parsed as "TLSv1.2" and " TLSv1.1", which is wrong.

Correct behavior: white spaces in "string arrays" should be ignored.
