[jira] [Created] (JEXL-131) UnifiedJexl (2.1.x) / Jxlt (3.0) parsing may fail with NPE

Henri Biestro created JEXL-131:
----------------------------------

             Summary:  UnifiedJexl (2.1.x)  / Jxlt (3.0) parsing may fail with NPE
                 Key: JEXL-131
                 URL: https://issues.apache.org/jira/browse/JEXL-131
             Project: Commons JEXL
          Issue Type: Bug
    Affects Versions: 2.1
            Reporter: Henri Biestro
            Assignee: Henri Biestro
             Fix For: 2.1.2, 3.0


>From Clay Bruce email:
the offending code is the method startsWith which can be found at line 1345 in UnifiedJEXL.java.
Problem is that sequence is not tested to see if the index is available before trying to access it.

A source with lines starting with leading spaces will trigger the bug.
