[digester3] - can DigesterLoader instance be shared?

[Torsten Krah <tk...@fachschaft.imn.htwk-leipzig.de>]

Hi,

Digester instance are not thread-safe as metioned by the docs. I wonder 
if a DigesterLoader instance can be shared between different threads, if 
each thread does create its own Digester instance via newDigester() - or 
should each thread create its own Loader (all are using the same rules 
file).

So - is it safe to share it or not?

Thanks a lot for the feedbacks Torsten,

as I commented in the issue, it would be really helpful if you could
attach a testcase to reproduce the issue, in order to looking forward
to a possible fix.

Many thanks in advance!

Good to know - so if i get a ConcurrentModificationException from the 
digester codebase, i'll found a bug and should open a ticket (will post 
the link at this thread here when reported).
Thought i did something wrong sharing my loader ;).

Hi Torsten,
yes, a configured loader instace can be shared across multiple
components in the application, just create new Digester instance every
time you have to perform a parse (or put them in a pool of digesters
to save resources)

HTH,

Some addition:

According to the employee servlet @ 
http://commons.apache.org/digester/guide/binder.html , it should be 
possible to share a loader, shouldn't it?
