Yup.  But you can also clean it out of the session yourself.

main struts controller servlet, and out of reach of any other threads?

Depends on what you mean.  If it's a read-only collection, then sure, it's "thread safe".
 But if you expect that list to change, then no, it's not thread-safe, because multiple
requests from the same user would be able to access the collection.
