Javac crashes with an assertion error in Types.contained by when compiling the following source:

import java.util.*;

class Test {
    <T> void m(T t, List<? super List<T>> list) {}
    void test(List<? super List<?>> list) {
        m("", list);
    }
}

In order to reproduce this problem the following command should be executed:

java -Xbootclasspath/p:/dist/lib/javac.jar -esa -jar dist/lib/javac.jar Test.java

or, using a JDK 7 compiler:

javac -J-esa Test.java
