UnsupportedRepositoryOperationException when using OR and LOWER()

I am just getting started to use JackRabbit queries and facing this issue. This query is semantically rational but it shows Unsupportedxxx. Remove LOWER(), it runs without error. Is this a bug of JackRabbit? How can I fix it?

Query

SELECT t.*
FROM [nt:base] AS t
WHERE t.[jcr:primaryType] = 'someType'
    OR (LOWER(NAME(t)) = 'a')

Exceptions

javax.jcr.UnsupportedRepositoryOperationException: null

Solution

  • Ticket filed at https://issues.apache.org/jira/browse/JCR-4234

    A workaround is to use 

    ... OR LOWER(LOCALNAME(t)) LIKE ...
