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)
