> HQL:
> SELECT o FROM EntityBean AS o, IN (o.items) AS l WHERE l.itemValue = '1'
> The log output gives the following:
> 2010-11-10 16:03:53,286 DEBUG [org.hibernate.hql.ast.QueryTranslatorImpl] (WorkerThread#0[127.0.0.1:60518]) parse() - HQL: SELECT o FROM EntityBean AS o, IN (o.items) AS l WHERE l.itemValue = '1'
> 2010-11-10 16:03:53,290 DEBUG [org.hibernate.hql.PARSER] (WorkerThread#0[127.0.0.1:60518]) Keyword  'AS' is being interpreted as an identifier due to: expecting IDENT, found 'AS'
> 2010-11-10 16:03:53,403 ERROR [org.hibernate.hql.PARSER] (WorkerThread#0[127.0.0.1:60518]) line 1:48: unexpected token: l
> According to the jpa persistence spec the AS keyword is optional for collection declarations:
> collection_member_declaration ::=
> IN (collection_valued_path_expression) [AS] identification_variable
> In hql.g we have:
> inCollectionDeclaration!
>    : IN! OPEN! p:path CLOSE! a:alias
>      { #inCollectionDeclaration = #([JOIN, "join"], [INNER, "inner"], #p, #a); }
>    ;
> Should this be a:asAlias rather than a:alias?
> Workaround: Do not use option AS, only identifier in the HQL for collection.
