Bug 27247

Description Olivier Thomann 2002-11-27 10:57:04 EST

Using 1119, we have a case where we should throw a NPE earlier. We do it, but
too late (inside the member constructor).

class A {
	class B {
		B(int i) {
		}
	}
	public static void main(String[] args) {
		int i = 1;
		try {
			A t = null;
			t.new B(i++);
		} catch (NullPointerException e) {
			System.out.println(i);
		}
		try {
			((A) null).new B(i++);
		} catch (NullPointerException e) {
			System.out.println(i);
		}
	}
}

We generate a getClass() inside the member constructor, but it should be done
before the constructor call if we don't want the side effect on 'i' (i++). Javac
1.4.1 adds the getClass() call before the constructor call in the outer class A.
I can give the bytecodes if needed.

In this case, the expected output is:
1
1
But we have:
2
3

In 1.3 mode, we don't throw any exception at all. Javac 1.3 has the same issue.
