hi! when running the latest TCK I get the following errors over here in Austria
[ERROR] Failures: [ERROR] NumberFormatCustomizationTest.testNumberFormatAccessors:135 Failed to correctly customize number format during marshalling using JsonbNumberFormat annotation on getter. Expected: a string matching the pattern '\{\s*"instance"\s*:\s*"123,456.79"\s*\}' but: was "{\"instance\":\"123.456,79\"}" [ERROR] NumberFormatCustomizationTest.testNumberFormatPackageTypeOverride:159 Failed to correctly override number format customization using JsonbNumberFormat annotation on package during marshalling using JsonbNumberFormat annotation on type. Expected: a string matching the pattern '\{\s*"instance"\s*:\s*"123,456.79"\s*\}' but: was "{\"instance\":\"123.456,79\"}" [ERROR] NumberFormatCustomizationTest.testNumberFormatType:89 Failed to correctly customize number format during marshalling using JsonbNumberFormat annotation on type. Expected: a string matching the pattern '\{\s*"instance"\s*:\s*"123,456.79"\s*\}' but: was "{\"instance\":\"123.456,79\"}" [ERROR] NumberFormatCustomizationTest.testNumberFormatTypeFieldOverride:183 Failed to correctly customize number format during marshalling using JsonbNumberFormat annotation on type. Expected: a string matching the pattern '\{\s*"instance"\s*:\s*"123,456.8"\s*\}' but: was "{\"instance\":\"123.456,8\"}" Reason is likely that the numberformat is defined as @JsonbNumberFormat(value = "###,###.##") public class PackageCustomizedTypeOverriddenDoubleContainer But afaiu the , and . in DecimalFormat [1] does not stand for the character ',' and ',' but just for 'that decimal separator in your language' (which over here in Austria is a dot, and '.' stands for the comma separator (which over here in Austria is really a comma, not a dot like in english speaking countries). And that way I likely end up with getting non expected values. This now might be a failure in the TCK or it might be a TCK setup issue. But I didn't find any documents which specifies that we need to run with lang=en_EN Have I overlooked something? txs and LieGrue, strub [1] https://docs.oracle.com/javase/8/docs/api/java/text/DecimalFormat.html
