ParseException against a parenthesized single variable at the begginig position

[glassfishrobot]

Parsing an expression like

${(var)}

causes the following ParseException. It is a pathological pattern but was accepted before introducing lambda.

The parser is trying to interpret it as LambdaParameters. Some other examples:

**Good**${var}
${-(var)}
${(3)*4}

**Bad**${(var)*4}
