Subject [jira] [Created] (JEXL-120) Make ParseException work in sandboxed environment

Make ParseException work in sandboxed environment
-------------------------------------------------

                 Key: JEXL-120
                 URL: https://issues.apache.org/jira/browse/JEXL-120
             Project: Commons JEXL
          Issue Type: Improvement
    Affects Versions: 2.0.1
            Reporter: Lukas Krecan


We execute JEXL expressions in sandboxed environment (using Java policy mechanism). When the
expression is incorrect, the {{org.apache.commons.jexl2.parser.ParseException}} is thrown.
Unfortunately it tries to access {{System.getProperty("line.separator", "\n")}} which fails
if access to system property is not allowed. 

{code}
java.security.AccessControlException: access denied (java.util.PropertyPermission line.separator
read)
