Bug in eclipse compiler or in javac ("type parameters of T cannot be determined")

The following code

public class GenericsTest2 {

    public static void main(String[] args) throws Exception {
        Integer i = readObject(args[0]);
        System.out.println(i);
    }

    public static <T> T readObject(String file) throws Exception {
        return readObject(new ObjectInputStream(new FileInputStream(file)));
        // closing the stream in finally removed to get a small example
    }

    @SuppressWarnings("unchecked")
    public static <T> T readObject(ObjectInputStream stream) throws Exception {
        return (T)stream.readObject();
    }
}

compiles in eclipse, but not with javac (type parameters of T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,java.lang.Object).

When I change readObject(String file) to

    @SuppressWarnings("unchecked")
    public static <T> T readObject(String file) throws Exception {
        return (T)readObject(new ObjectInputStream(new FileInputStream(file)));
    }

it compiles in eclipse and with javac. Who is correct, the eclipse compiler or javac?
