NPE in LocalDeclaration.resolve when performing content assist with an anonymous class in a lambda body. Same problem with a local class.

package jsr335;
import java.util.function.IntFunction;
public class Snippet {
    void foo() {
        IntFunction<String> toString = i -> {
            //<-- Ctrl+Space here
            new Runnable() {
                @Override
                public void run() {
                    //<-- Ctrl+Space here
                }
            }.run();
            return Integer.toString(i);
        };
    }
}

Stacktrace in bug 383096 looks similar, but that bug is about code with a syntax error.
