Subject [jira] [Created] (POOL-232) GOP: borrowObject() & returnObject() are still not FIFO

deepak created POOL-232:
---------------------------

             Summary: GOP: borrowObject() & returnObject() are still not FIFO
                 Key: POOL-232
                 URL: https://issues.apache.org/jira/browse/POOL-232
             Project: Commons Pool
          Issue Type: Bug
    Affects Versions: 1.6
            Reporter: deepak


Latest Pool API (1.6) is still not implemented the fairness policy, because of the usage of
the synchronized construct in the two important borrowObject() & returnObject() APIs

If you have very high no. of clients threads, trying to invoke either borrowObject() &
returnObject() APIs, then their order will not be respected because synchronized keyword doesn't
guarantee the fairness. ReentrantLock could be used in both the APIs in order to have the
fairness policy implemented.

Though in the past, someone raised the exact same issue (POOL-75), but don't really understand
that how it is fixed when issue seems to be still present.

I am from telecom industry, and I use this library in the reall time call flow, so for me
fairness is very important.
