The initial analysis was correct as confirmed by Yannick. The problem is not solved in Hibernate 4.1.4 as shown by the test case attached to HHH-7374.
Steve Ebersole June 6, 2012 at 5:59 PM
Then upload a test case. There is a reason we ask for those...

Sorry to bother you with this again, but I must be stupid. I upgraded to Hibernate 4.1.4 Final. Same query, same error:

I looked at the test case org.hibernate.test.hql.ASTParserLoadingTest and I noticed two things:
1. It only has tests for the 'key' and 'entry' keyword, not the 'value' keyword. I didn't find one anywhere else.
2. It only tests for the keyword when it is used in the 'select' portion of the statement, not the 'where' portion like we're trying to do. Could it be that these keywords are only recognized in the 'select' part?

this is fixed, I'm assigning it back to you and mark this as resolved.
Strong Liu May 31, 2012 at 5:16 AM
I think it is a typo in L281:
the second "form" should be "join", committing the fix
The KEY() and VALUE() operators for persistent maps do not seem to be implemented in Hibernate.
E.g. consider the query
given the following classes and mappings.
(Note that these mappings are similar to but slightly different from the ones I used in HHH-5393. This time the map key column has a different name, creating a redundant column I would have liked to avoid. That way, Hibernate is at least happy about the mapping.)
Running the query, I get the following exception:

Using upper-case 'KEY(m)', the exception is different:

(The message from PostgreSQL means "Function key(bigint) does not exist".)
I had a look at the ANTLR grammar for the query parser a while ago (which may have been before 3.5.3), and as far as I could make out, key() and value() are only recognized as lower case keywords, and while the parser accepts the syntax, it fails to generate any appropriate actions.
The stack traces are up-to-date though, I just ran my test cases on Hibernate 3.5.3.
