Bela Ban commented on JBCACHE-461:
----------------------------------
Hmm, from the documentation of ReentrantReadWriteLock:
"
# Lock downgrading
Reentrancy also allows downgrading from the write lock to a read lock, by acquiring the
write lock, then the read lock and then releasing the write lock. However, upgrading from
a read lock to the write lock is not possible.
"
Upgrading is essential for JBossCache, so we should inquire (concurrency-interest mailing
list) *why* this is not supported.
Potential bug in ReentrantWriterPreferenceReadWriteLock from
