Crash with -XDfind=lambda and -source 7

Consider the following code:
---
import java.util.*;

public class AnalyzerBug {
    private void t(boolean b) {
        (b ? Collections.emptyList() : new Iterable<String>() { public Iterator<String> iterator() { return null; } }).toString();
    }
}
---

Compilation with -XDfind=lambda and -source 7 leads to a crash in Analyzer:
---
$ javac -XDfind=lambda -source 7 /tmp/AnalyzerBug.java
warning: [options] bootstrap class path not set in conjunction with -source 7
warning: [options] source value 7 is obsolete and will be removed in a future release
warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.
