Adithyan K commented on GROOVY-8957:
Calling `as int` to convert a String to int is perfectly ok.
The point I was concerned is the difference between 'Line-5' and 'Line-10'.
Both lines are assigning a `String` (Data type is perfectly String. The
previous line confirms it) to an `int` variable without `as int`.
Line-10 shouts as CastException as it is more than 1 length and Line-5 silently
assigns the ascii value 49 to the int variable.
If I read your answer as `Groovy treats Strings with length 1 always as char
for all purposes`, then this issue can be closed.

/*line 1 : case-1 */ charc1 = '1'

Case-1
Line 3 prints `49`. It is ok as `char` is assgined to integer in line 2
Case-2
Line 7 prints `n21` eventhough String is assgined in line 5... Is it right?
Line 6 : `n22` is assigned 1 as I have written `s2 as int`. This is ok
Case-3
Line 10 : Throwing GroovyCastException. This is ok.
The difference between Line-5 and Line-10 is the difference in String length.
Both are Strings. The former is of length 1 and the latter is of length 2.
So, String with length 1, if assigned to int variable, assigns the ascii value.
String with more than 1 length throws GroovyCastException This looks some what
different...
Is it the acceptable behavior
