Hi, Your test is incorrect. This lines are not synchronized and can be reordered with each other and with the validation that happens in another thread:
simpleCacheValidationWithLock.setIndex(i - 1); simpleCacheValidationWithLock.setValueToValidate(valueCounter); After I moved them into the synchronized block, test always passes. BTW, for such transactional updates it's better to use PESSIMISTIC/REPEATABLE_READ transactions: https://apacheignite.readme.io/docs/transactions -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Getting-previous-value-in-cache-immediately-after-performing-an-unlock-tp10236p10254.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
