frontend bug -- inner classes

[Adam Megacz <gcj at lists dot megacz dot com>]

This should not compile, yet it does. Note that x is not static, yet
main() is.

public class t {
    int x = 0;
    public static void main() {
        new Thread() {
                public void run() {
                    x = 5;
                }
            }.start();
    }
}

javac gives this error:

t.java:6: non-static variable x cannot be referenced from a static context
                    x = 5;
                    ^
