DBMS_METADATA generating incorrect syntax for the CREATE TABLE statements with ROW ARCHIVAL enabled (12.1.0.2)

While experiencing with the In-Database Archiving feature in 12.1, I stumble upon this unpublished bug with DBMS_METADATA.GET_DDL.

The clause "ILM ENABLE LIFECYCLE MANAGEMENT" was returned instead of "ROW ARCHIVAL" which causing an ORA-00933 at creation time. And here is what I found on My Oracle Support about this issue who is also impacting datapump imports in 12c:

CAUSE
The cause of this problem has been identified in:
unpublished Bug:17653443 - DBMS_METADATA.GET_DDL GENERATES WRONG DDL FOR TABLE WITH ROW ARCHIVAL
closed as duplicate of:
unpublished Bug:17654567 - DATA FROM ROW ARCHIVAL COLUMN ORA_ARCHIVE_STATE NOT TRANSFERRED WITH DATA PUMP
It is caused by DBMS_METADATA generating incorrect syntax for the CREATE TABLE statement in the dump file.
Bug:17654567 is fixed in RDBMS 12.2.
