In the following example, t is null, yet the method simpleMethod is called
rather than a NullPointerException being signaled. The println in simpleMethod()
prints This is <Null Object> which is completely wrong.

There must be a missing null check in invokenonvirtual, which is the opcode being
generated by the compiler (since simpleMethod is a private method).

public class test {
    static void staticTest() {
test t = null;

t.simpleMethod();
    }

    private void simpleMethod() {
System.out.println("This is " + this);
    }

    public static void main(String args[]) {
staticTest();
    }
}
