If we do not have any protective mechanics (need to check), then this > call may lead to cache creation on a client, which in turn will wait for all > TXes to finish, including current one, leading to a deadlock. > # Create tests confirming the problem > # If hang is reproduced - add a check for ongoing transaction and throw an > exception -- This message was sent by Atlassian JIRA (v7.6.3#76005)
