Pass configured locale to SimpleDateFormat in DateTimeConverter

[rootvector2]

getFormat(String) builds the pattern SimpleDateFormat with the jvm default locale and ignores the converter's configured locale, so a converter given both setLocale and a pattern parses and formats month and day names in the default locale instead of the configured one; pass locale when it is set, matching DateLocaleConverter and StringLocaleConverter. found auditing locale handling across the date converters.

Hi @rootvector2 Please see my comment.

Use JUnit Pioneer to set a temporary Locale.

[rootvector2]

Done, switched the test to Pioneer's @DefaultLocale and dropped the manual save/restore. Added junit-pioneer as a test dependency since it wasn't in the pom yet (version comes from commons-parent). All 9 subclass runs still pass.
