Query about CONFIGURATION-390, a threading problem in
commons-configuration reloading
What's the activity on resolving CONFIGURATION-390? I see it's slated to be
fixed in 1.7, but how likely is that to happen? This threading issue is
killing me. I'd rather not have to synchronize every every configuration
call just because I need to be able to reload the configuration when the
file changes. Is the plan to still support the thread-safety claim that Oliver
Heger made back in 2006 (
http://www.mail-archive.com/commons-user@jakarta.apache.org/msg14490.html)?
Thanks,
Stephen Kinser

I am running into this into production. I will have to attack this
over the weekend. I'm sure it won't be pretty. At least on the 2.0
branch we can start using read/write locks. In 1.7 it will have to use
synchronize(), probably in many places.

I cannot promise when I come to it, but I am going to have a look at
this issue. The goal is still that read-only access to a configuration
should be thread-safe.
