I'm trying to use Tools|Synchronize to add
<T> T[] toArray(T[]) from java.util.Collection
on this program:

package com.sun.tools.javac;
import java.util.AbstractList;
import java.util.List;
public class LazyList<E> extends AbstractList<E> {
    
    /** Creates a new instance of LazyList */
    public LazyList() {
    }

    public E get(int index) {

        throw new UnsupportedOperationException();
    }
    
}

Details:
