I believe this is a compiler error, not an error in the code. `value'
is not being initialized with a value of type int, but with a value of
type char. JLS 15.24:
The type of a conditional expression is determined as follows:
...
Otherwise, if the second and third operands have numeric type,
then there are several cases:
...
If one of the operands is of type T where T is byte, short, or
char, and the other operand is a constant expression of type
int whose value is representable in type T, then the type of
the conditional expression is T.
