Well, strictly speaking, a pointer alone is not harmful and quite
impossible since the field is for example package local in the
AbstractStringBuilder class and the accessor is also package local.

The problem is invoking a method of an object that has access to
the char[] and will do some write into the array between offset
and offset+count of the string.
