I think I know what the problem is looking at the code:
In SegmentInfos.java (line 321):
class SegmentInfos extends Vector
{
public Object clone() {
SegmentInfos sis = (SegmentInfos) super.clone();
for(int i=0;i<sis.size();i++) {
sis.setElementAt(((SegmentInfo) sis.elementAt(i)).clone(), i);
}
return sis;
}
}
We see that it is trying to cast a Vector into SegmentInfos which explains
the ClassCastException. This is definitely a bug.
