Ilya Lantukh commented on IGNITE-4931:
--------------------------------------

[~Alexey Kuznetsov],
Tests look good, but you should also specify in ignite.active(boolean) method's javadoc that
it will throw exception in such use case.

> Currently deactivation process, started after transaction start or cache lock on key
hangs waiting transaction end\ cache unlock. Closing transaction\unlocking the lock leads
to excpetion when deactivation is in progress. It looks like 'deadlock'. 
> So, expected behaviour: starting deactivation should lead to excpetion if transaction
is in progress or cache key is locked.
> Exception should be thrown like in case when we start cache and transaction is in progress
(see checkEmptyTransactions method). In new tests we should run transactions\lock in the same
thread as deactivation started
