--- Comment #3 from Stefan Bodewig <bode...@apache.org> --- If you omit the pattern Ant uses "new DecimalFormat()" which uses the decimal format for your locale (the FORMAT one https://docs.oracle.com/javase/8/docs/api/java/util/Locale.Category.html#FORMAT to be precise). It is very common for the locale specific format to contain a thousands-separator which in a German locale 1000 would be formatted as 1.000 for example. -- You are receiving this mail because: You are the assignee for the bug.
