I am running into an internal compiler error in 3.2 that worked fine in 3.1. It seems to occur when I want to use a method implementation in an abstract superclass but have a method of the same name (but different signature) with default visibility in the concrete class.

Here's a simple test case:

package package1;

import package2.MyList;

public class Test {
	public void reproduce(String sortKey, boolean isAscending) {
		MyList recList = new MyList();
		recList.add(null);
	}
}

...

package package2;

import java.util.AbstractList;
import java.util.List;

public class MyList extends AbstractList implements List {

	void add(Integer i) {
	}
	
	public Object get(int index) {
		// TODO Auto-generated method stub
		return null;
	}

	public int size() {
		// TODO Auto-generated method stub
		return 0;
	}
	
}
