[dom4j-user] list.addAll() throws unsupportedOperationException under Java 5

[Joel Rosi-Schwartz]

Hi,

I've ran into an odd problem after moving my application over to Java 5. The
code below worked fine under Java 1.4.x but it nows throws an
unsupportedOperationException. I have also tried and iterator and add() but
I get the same problem. I appears that for some reason the list I am getting
back from selectNodes is now readonly.

   List nodes = DocumentHelper.selectNodes("./MasterAssembler/MECP",
rootElement);
 nodes = addAll(nodes, DocumentHelper.selectNodes(".//SubAssembler/MECP",
rootElement));

Any ideas on what is happening and how to rectify it. Btw, for the moment I
a simply creating an ArrayList and copying both lists into it.  This works
fine in this instance because I am not manipulating the list. But in the
future I am sure I will run into a problem with this kludge.

Thanks,
Joel
