--- Comment #2 from Dominik Stadler <dominik.stad...@gmx.at> --- I am wondering why we even use synchronization here at all. Our thread-safety guarantee does not allow to use one workbook/doc/item in more than one thread at a time anyway. So this synchronization is not really necessary as we ask our users to perform synchronization at an upper level anyway, if they want to access documents across different threads... Having all of POI fully thread-safe would require many many points of synchronization and would cause a performance penalty for many current power-users. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
