Apparently @Enumerated annotation does not apply to an array of enum values.
When I take it away as shown below,
@Column(nullable=false)
@Basic( fetch = FetchType.EAGER )
//@Enumerated( EnumType.STRING )
private Measure[] measures;
I am able to persist the entity. Query also returns a correct array of enum
values. According to the documentation, the @Enumerated annotation controls how
the field maps to the database, i.e., String or Ordinal. For array and
collection, the field is mapped to Blob in the database.
