[24] ECJ generates wrong code for primitive pattern with instanceof

[jarthana]

Given the code,

	static Integer getInteger() {
		return Integer.MIN_VALUE;
	}
	public int foo() {
		Y<Integer> f = new Y<>();
		f.put(X.getInteger()); // This makes all the difference
		return f.get() instanceof float ? 3 : 2;
	}

Compiled and run, this returns 3 with ECJ but returns 2 with Javac. Inspecting the compiled output, I see this from ECJ:
19: instanceof #3 // class java/lang/Object

which I believe is wrong. With Javac, it's Integer.

BTW, Y is defined as below:

class Y<T> {
    T a;
    T get() {
        return a;
    }
    void put(T val) {
        a= val;
    }
}
