Alexander Shraer edited comment on ZOOKEEPER-2080 at 7/27/16 12:07 AM: ----------------------------------------------------------------------- Hi Michael, thanks for the patch, it looks good to me. I have two questions: do you think that the creation of a new election object won't be interfered if the old object shutdown/GC hasn't happened yet ? and any way to test this using a unit test ? Since you're doing stress tests I'm less worried if a unit test is complicated. You'd probably have to somehow suspend a messaging thread to create the deadlock, not sure. was (Author: shralex): Hi Michael, thanks for the patch, it looks good to me.
