Diamond operator type inference fails under javac but not ECJ

The following minimal example produces a compiler error under javac but not ECJ:

```java
import java.util.List;
import java.util.ArrayList;
import java.util.Arrays;

public class HelloWorld {
public static void main(String... args) {
Class[] classes = new Class[] { String.class, List.class };
List> asdf = new ArrayList<>(Arrays.asList(classes));
}
}
```

Here's the error that javac gives:

```
HelloWorld.java:9: error: incompatible types: cannot infer type arguments for ArrayList<>
List> asdf = new ArrayList<>(Arrays.asList(classes));
^
reason: cannot infer type-variable(s) E,T
(argument mismatch; List cannot be converted to Collection>)
where E,T are type-variables:
E extends Object declared in class ArrayList
T extends Object declared in method asList(T...)
```
