Alexander Klimetschek commented on JCR-3713:
--------------------------------------------
The fix should be simple: if "conditions" is empty, simply add the expression
directly and ignore optional (OR).
> 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.
