    [ https://issues.apache.org/jira/browse/JENA-2019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17283965#comment-17283965 ]

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

I pulled the repo 2 days ago, the commit I used is on *master*: 4321d11a9bfef4258104860c44b5d6d1991f5790 
 (I will use *main* next time, thank you).

The code I originally posted: 
{code:java}
# Rule including string "("
[(?a my:text "(") -> ]
{code}
still does not work (the first FAIL in my pastebin snippet).

I used jdk14 for maven to compile *jena-core* only and substituted my project dependency on jena-core:3.17.0 with the built 3.18.0-SNAPSHOT. Maybe I have to rebuild more modules?

I used both openjdk 8 and jdk14 to run my code and experiences the same behaviour (as reported in the pastebin snippet).
How can I check my environment is OK?

> I have some [Jena rules|https://jena.apache.org/documentation/inference/#RULEsyntax] and I {color:#172b4d}need {color}to test a string literal in them:

> {code}

> List<Rule> rules = Rule.rulesFromURL(my_rules_path)
> {code}
> throws:

> Exception in thread "main" org.apache.jena.reasoner.rulesys.Rule$ParserException: Expected ')' at end of clause, found ]

> This crash happens if the string is exactly equal to *"("* (the use of double quotes or single quotes does not matter). Escaping also with backslash *"\ ("* does not help.
>  Changing the original string from *"("* to *"()"* , *"(("* , *"-("* or *")"* eliminates the exception (but this is not what i want).
