Given the following illegal program, the compiler enters what appears to be an
infinite loop:

    public class Bug {

private void foo() {
}

private Thread bar
= new Thread() {
public void run() {
for (;;) {
Bug.this.foo();
}
}
};

    }

If the for loop is removed but the invocation of foo() left intact, then the
compiler terminates. Both behaviors are wrong since foo() is private and
access to it should not be allowed. The 1.1 compiler gets this right, but
seems to have another problem:

    % /usr/local/java/jdk1.1/solaris/bin/javac Bug.java
