[jira] [Created] (SPARK-5009) allCaseVersions function in SqlLexical leads to StackOverflow Exception

shengli created SPARK-5009:
------------------------------

             Summary: allCaseVersions function in  SqlLexical  leads to StackOverflow Exception
                 Key: SPARK-5009
                 URL: https://issues.apache.org/jira/browse/SPARK-5009
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.2.0, 1.1.1
            Reporter: shengli
             Fix For: 1.3.0, 1.2.1


Recently I found a bug when I add new feature in SqlParser. Which is :
If I define a KeyWord that has a long name. Like：
 ```protected val ：SERDEPROPERTIES = Keyword("SERDEPROPERTIES")```

When  ```implicit asParser`` function is called , lexical.allCaseVersions will leads SO Exception since this function will generate huge number of possible cases in stack.
