>             Project: Commons JEXL
>          Issue Type: Bug
>    Affects Versions: 3.1
>            Reporter: Constantin Hirsch
>            Assignee: Henri Biestro
>            Priority: Major
>             Fix For: 3.2
>
>
> In the TemplateEngine, inside an Inline-Expression, a String literal containing a curly brace leads to a parser error.
>  
> To reproduce, just run this code:
> {code:java}
> new JexlBuilder().create().createJxltEngine()
>     .createTemplate("${\"{\"}").evaluate(new MapContext(), new StringWriter());
> {code}
> The Exception is either "malformed expression" or "tokenization error", depending on if the inner curly brace is opening or closing.
>  
> The problem lies in the parsing state machine of TemplateEngine.parseExpression(). It does not recognize the String literal.
