#1201 Error "Can't find resource null" when ruleset contains spaces after comma

[Los Pejos]

Error "Can't find resource null" when ruleset contains spaces after comma. Consider trimming strings (ruleset names) after splitting comma-separated by separator (commas):
Example:
1) configuration.setRuleSets("ecmascript-basic,ecmascript-braces,ecmascript-unnecessary") is ok
2) configuration.setRuleSets("ecmascript-basic, ecmascript-braces, ecmascript-unnecessary") leads to error "net.sourceforge.pmd.RuleSetNotFoundException: Can't find resource null. Make sure the resource is a valid file or URL and is on the CLASSPATH."

Will be fixed with the next version.
