[jira] [Commented] (CMIS-1051) OOM when parsing string with double quotes

["Jens Hübel (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CMIS-1051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16257023#comment-16257023 ] 

Jens Hübel commented on CMIS-1051:
----------------------------------

Michael did you run your tests with Java 9?

I can reproduce the problem with Java9, an older version of opencmis with Java 7 passes your test.
The problem occurs in the ANTLR runtime, which might be incompatible with Java 9.

I guess the version of ANTLR is a bit outdated (2014). An update to ANTLR 4 would be a huge change as it implies a rewrite of the grammar. ANTLR4 is incompatible to ANTLR3. 

I will look a bit deeper and try to understand why it fails.

> parsing a query with an incorrect string literal using double quotes (") iso of single quotes (') leads to an OOM exception
> example query:
> {noformat}
> SELECT * FROM cmis:document WHERE cmis:name = "a"
> {noformat}
> testcase for TestParserStrict
> {noformat}
>     @Test
>     public void queryDoubleQuotes() throws Exception {
>         testParserFail("query", "SELECT * FROM cmis:document WHERE cmis:name = \"a\"");
>     }
> {noformat}
> stacktrace:
> {noformat}
