Here is an overview of the issue:
---------------------------------------------------------------------
Key: JELLY-8
Summary: jexl parse error
Type: Bug
Status: Assigned
Priority: Major
Time Spent: Unknown
Remaining: 0 minutes
Project: jelly
Assignee: james strachan
Reporter: Jason Horman
Created: Sat, 28 Sep 2002 3:10 AM
Updated: Sat, 28 Sep 2002 3:10 AM
Environment: java version "1.4.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)
Description:
The following jelly script:
<jelly xmlns="jelly:core" xmlns:log="jelly:log" xmlns:bsh="jelly:beanshell">
<set var="testStr" value="hello"/>
<log:info>${testStr.charAt(-2)}</log:info>
</jelly>
Throws the exception below. Changing the number to positive fixes the error. I realize this would cause an OOB but it is just to demonstrate that something seems to be wrong with the parsing of the expression.
