Struts 1 Actions are singletons and must be thread-safe
since there will only be one instance of a class to handle
all requests for that Action. The singleton strategy places
restrictions on what can be done with Struts 1 Actions and
requires extra care to develop. Action resources must be
thread-safe or synchronized.
Struts 2 Action objects are instantiated for each request,
so there are no thread-safety issues. (In practice, servlet
containers generate many throw-away objects per request, and
one more object does not impose a performance penalty or
impact garbage collection.)
