Improve error message for '->' instead of '-->'

[insafuhrmann]

When mistakenly writing // XPECT errors -> "..." at "..." instead of // XPECT errors --> "..." at "...", the error message is not helpful, see following stack trace in Eclipse.

I didn't understand this problem . what is the problem in it ?

If you use that bad expect statement you should get an error message telling it instead of just null pointer

[Nishantware]

Null pointer nothing but the type of error message when you use an uninitialized variable is used.
