Reports ambiguous accesses of a super class field from an inner or anonymous class, where a local variable, parameter or field with identical name is available
in the surrounding code. In this situation a cursory examination of the code may suggest that an element in the surrounding code is
accessed, when in actual fact a field from the super class is accessed. To clarify the intent of the code it is recommended to add a
super qualifier to the field access.
Example:
class X {
protected String s;
}
class Y {
void foo(String s) {
new X() {{
System.out.println(s); // here the field is accessed not the parameter
}};
}
}
