Please report bugs using ASF's JIRA instance for Jena. General suggestions or requests for changes can also be discussed on the user list, but are less likely to be accidentally forgotten if you log them into JIRA.
Patches and other code contributions should also be attached to issues in JIRA (click on More Actions > Attach Files) or made via git pull requests. See ‘Getting Involved’
Please note that ASF requires that all contributions must be covered by an appropriate license.
