Eclipse fails with JDK8 build 111

Eclipse Version: Kepler Service Release 1
Build id: 20130919-0819

Can not execute the indexer with JDK8 build 111 due to a change in how java.lang.Object.clone() is treated.

The Eclipse CDT framework has a structure that uses a two level interface structure to create a clone() method that does not throw CloneNotSupportedException. This approach seems to work in b110 but stops working in b111.

I can reproduce the issue with this examle:

public interface IClone extends Cloneable {
Object clone();
}

public interface ICloneExtend extends IClone { }

public class CloneTest implements ICloneExtend {

public Object clone() {
return null;
}

public static void tryIt(ICloneExtend o1) {
Object o2 = o1.clone();
System.out.println(o1 + " was cloned to " + o2);
}

public static void main(String[] args) {
CloneTest o1 = new CloneTest();
tryIt(o1);
}

}


Here is the output:
