According to spec bugs: JDK-8373719 and JDK-8373721:
In JLS 6.5.6.1, references to fields are subject to a handful of restrictions
if they refer to instance fields. In 15.8 and 15.11, 'this.x' and 'super.x' are
intended to be viewed as instance field references, and subject to the same
restrictions.
So the following code should fail to compile:
class Test {
static final boolean check = true;
Test(int a) {
boolean b = Test.this.check; //compilation error expected here
this();
}
}
However, javac is currently accepting it
