5.2: Bad conversions are listed

A DESCRIPTION OF THE PROBLEM :
In the JLS for Java 15, section 5.2 (Assignment Contexts), the following conversions are listed:
   1) a widening reference conversion followed by an unboxing conversion
   2) a widening reference conversion followed by an unboxing conversion, then followed by a widening primitive conversion

These should probably say "narrowing reference conversion". For example, in:
    int x = (int) (Object) Integer.valueOf(3);
Object is narrowed to Integer, then unboxed. And in:
    int x = (int) (Object) "test";
Object is narrowed to Integer, which fails with ClassCastException at runtime.

The unboxable classes are all final and can't be subclassed, so they can not be widened.
   


FREQUENCY : always
