javac allows import statement for current class, contrary to JLS 8.1 p.129

When a java class contains an import statement which names itself,
fastjavac declares an error (and javac doesn't).

import A;
public class A {
 A() {}
}

A.java:2: Class name A clashes with imported class on line 1
public class A {
             ^
1 error

This turns up all over our code as a result of a preprocessor which expands
import statements with "*" to an explicit list of classes.
