MessageFormat not formatting when single quotes are included

My mistake was, that I didn't use the returned value from method 'format(..)'

Wrong code:

MessageFormat.format(sss, testArgs);
System.out.println(sss);

Correct code:

String newString = MessageFormat.format(sss, testArgs);
System.out.println(newString);

The single quote must be escaped using a double single quote:

String sss = "{0}SomeText{1}''.{2}S..."
