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

             Summary: unescaped single quotes lead to an OOM exception
                 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


when calling `org.apache.chemistry.opencmis.server.support.query.QueryUtilBase.processStatement()` 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}
"'';'" {code}
We run into an OOM exception with such stack trace:
{code:java}
