IBM JDK does not support some String.format specifiers
------------------------------------------------------
Key: JRUBY-3997
URL: http://jira.codehaus.org/browse/JRUBY-3997
Project: JRuby
Issue Type: Bug
Components: HelpWanted, IBM/Other VM
Reporter: Charles Oliver Nutter
Assignee: Thomas E Enebo
Fix For: JRuby 1.4
There's some cases, used by TimeOutputFormatter, that IBM's JDK's String.format
does not appear to support. here's the failures from CI:

Seems to trace back to the String.format call in this method:
{noformat}
private String padding(String sequence, String padder) {
if (formatter != null && formatter.contains("-")) return sequence;
if (sequence != null && sequence.length() < totalPadding) {
String format = String.format("%1$#" + totalPadding + "s",
sequence);
if ("0".equals(padder)) {
format = format.substring(0,
format.indexOf(sequence)).replaceAll(" ", "0") + sequence;
}
return format;
}
return sequence;
}
{noformat}
