javac exception compiling Lambda expression

[Roger Riggs]

In converting some anonymous inner classes to lambda expressions
I get a compiler stack trace.

Created issue JDK-8006140:

The offending test case .java file is:

public interface ChronoLocalDate1
         extends Comparable<ChronoLocalDate1> {

     // Original
     public static final Comparator<ChronoLocalDate1> DATE_COMPARATOR1 =
             new Comparator() {
         public int compare(Object date1, Object date2) {
             return 0;
         }
     };
     // Netbeans suggested turning the comparator above into this.
     public static final Comparator<ChronoLocalDate1> DATE_COMPARATOR3 =
             ( date1,  date2) -> 0;

}
