When concatenating two strings with one containing an 'e' character, an ArithmeticException is thrown.
The problem lies in the JexlArithmetic.isFloatingPointNumber() method in line 200.
return ((string.indexOf(46) != -1) || (string.indexOf(101) != -1) || (string.indexOf(69) != -1));
With this solution also the String "New York" or "hello.world" are floating point numbers. A solution with a regular expression would be better
