Jens Hübel commented on CMIS-1051:
----------------------------------
The problem is somehow in the lexer generator. The Java class generated from
AntLR with Java7 is different to the one from Java9:
public class CmisQlStrictLexer_CmisBaseLexer extends Lexer {
...
static final String DFA12_minS =
"\1\11\1\103\1\101\1\116\1\117\2\116\1\105\1\111\1\110\1\131\1\105\2\117"+
...
}
Java 9:
public class CmisQlStrictLexer_CmisBaseLexer extends Lexer {
...
static final String DFA12_minS =
"\1\47\1\103\1\101\1\116\1\117\2\116\1\105\1\111\1\110\1\131\1\105\2\117"+
...
}
One starts with 1, 47 the other one with 1, 11
In the debugger I see a tab character in the string (correct) and in the other
case a single quote (wrong).
This breaks the parsing. If someone has a clue what Java 9 feature may cause
this please comment.
> OOM when parsing string with double quotes
> ------------------------------------------

> Key: CMIS-1051
> URL: https://issues.apache.org/jira/browse/CMIS-1051
> Project: Chemistry
> Issue Type: Bug
> Components: opencmis-server
> Affects Versions: OpenCMIS 1.1.0
> Reporter: Michael Brackx
> Assignee: Jens Hübel
>
> 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}
