------------------------------------
Hola Mau,
after all the effort you put on this issue I have nothing against the merge,
but please - don't get me wrong! - for a better appliance of the Apache Way,
announce what you are going to do before, personally I didn't realize you
terminated - saw continue activity on the merge - in order to have a general
consensus.
Minor question: can I merge now the performances tests in the current
{{/trunk}}? TIA!
Thanks a lot for taking care of it!

> I've noticed a lot of synchronized blocks of code in OGNL. For the most part,
> these synchronized blocks are controlling access to HashMaps, etc. I believe
> this could be done far better using ReentrantReadWriteLocks.
> ReentrantReadWriteLock allows unlimited concurrent access, and single threads
> only for writes. Perfect in an environment where the ratio of reads is far
> higher than writes; which is typically the scenario for caching. Plus the
> access control can be tuned for reads and writes; not just a big
> synchronized{} wrapping a bunch of code.
