There was a problem hiding this comment.
@ramanathan1504, pattern-layout.adoc needs to be updated. Would you mind doing that too, please?

Fixes #4129
DatePatternConverter incorrectly interpreted locale-like second arguments (for example de-DE) as timezone IDs when no timezone was provided.
This caused patterns like %d{dd-MMMM-yyyy}{de-DE} to use the JVM default locale instead of the requested locale, producing incorrect localized month names.
This change tightens locale detection so locale tags are correctly recognized in the 2-argument form, while preserving existing behavior for the 3-argument form %d{pattern}{timezone}{locale}.
