JavaTest Message: Test threw exception: java.util.MissingFormatArgumentException: Format specifier '%s'
JavaTest Message: shutting down test

STATUS:Failed.`main' threw exception: java.util.MissingFormatArgumentException: Format specifier '%s'

99: if (!received) {
100: System.out.printf("%s: Unexpected headers received: dropping request.%n");
101: continue;
102: }

should be
System.out.printf("%s: Unexpected headers received: dropping request.%n", name);

BUT could be viewed as javac issue i.e. missing args detected as compile time, same as with C compiler
