             Summary: Array parsing gives inconsistent results when no data 
present
                 Key: JEXL-183
                 URL: https://issues.apache.org/jira/browse/JEXL-183
             Project: Commons JEXL
          Issue Type: Bug
    Affects Versions: 2.1.1
            Reporter: Richard Tomlinson


Create expression and execute with a result of false:   foo.0 == "Napa"
Same expression with [] tries to evaluate "Napa" as numeric so a 
NumberFormatException is thrown for:  foo[0] == "Napa"

java.lang.NumberFormatException: For input string: "Napa"
