------------------------------------------

             Summary: NPE in GQL if it starts with OR expression
                 Key: JCR-3713
                 URL: https://issues.apache.org/jira/browse/JCR-3713
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-jcr-commons
    Affects Versions: 2.7.3
            Reporter: Alexander Klimetschek


These GQL queries lead to an NPE:

    OR property:something
    path:/content OR property:something

This is because GQL#pushExpression() will blindly replace the previous entry in 
the "conditions" list, even if it is still empty.
