A DESCRIPTION OF THE PROBLEM :
The SimpleDateFormat add an extra point for short month names (pattern MMM) in German. This extra point is needing for parsing and also print on formatting a data. It look like the localized names contains the extra point. For the English locale it is working like expected.

With Java 17 the parsing is failing which make the problem visible. With Java 11 the formatting is already wrong.

REGRESSION : Last worked in version 11.0.11

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test program.
