-----------------------------------
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}
