Missing code implementation in the compiler [message #1868088]

Hello. This error is not critical, but this difference in behavior confused me. The problem is in the code that creates an anonymous class, inside of which there is a static method that accesses a local variable. javac does not compile such code at all, while eclipse compiles the code successfully if assignment is constant.
I.e. if testLocal = foo() javac gives 'error: non-static variable testLocal cannot be referenced from a static context' and eclipse gives 'missing code implementation in the compiler'.
If testLocal = 1 javac gives the same error but eclipse compiles code successfully and code can be executed.

public class Main {
    private static int foo() {
        return 1;
    }

    public static void main(String[] args) {
        final int testLocal = 1;
        Object obj = new Object() {
            public static void foo() {
                System.out.println(testLocal);
            }
        };
        try {
            obj.getClass().getMethod("foo").invoke(null);
        } catch (Throwable t) {
            t.printStackTrace();
        }
    }
}
