Hi I asked similar question and yet did not get an
answer, I dont know why its happening in my case,
however, I know that ConcurrentModificationException
is thrown when a thread is trying to modify a
collection while another thread is still iterating it.
Dont know if it helps you or not sorry.
You don't need two threads.
If you are using an iterator and are removing from the
collection you are iterating over - you will get this
error.
If you are using EJB CMP then you need to know how
relationships work because it is easy to run into
this.

This is occuring from inside an ActionForm validate
