> Key: CMIS-1120
> URL: https://issues.apache.org/jira/browse/CMIS-1120
> Project: Chemistry
> Issue Type: Bug
> Components: opencmis-server
> Affects Versions: OpenCMIS 1.1.0
> Reporter: Nour Al KOTOB
> Priority: Major
>
> when we call
> {noformat}
> org.apache.chemistry.opencmis.server.support.query.QueryUtilBase.processStatement(){noformat}
> with a statement containing an unescaped single quote like:
> {code:java}
> "SELECT cmis:objectId FROM cmis:folder WHERE dc:title = '';'"{code}
> or even just
> {code:java}
> "'';" // but "''a" throws an expected CmisInvalidArgumentException so the
> semi colon is important...{code}
> We run into an OOM exception with such stack trace:
> {code:java}
