| Side note: this bug would also impact anyone who upgraded to 1.50 following the suggested process (kill all executors, upgrade plugin, restart) upon reboot of Jenkins if executors were not all wiped out before shutdown - because this is a serialization bug, any deserialization was failing with 1.50 (we just ran into this on a Jenkins server I managed, and the upgrade to 1.50.1 fixed it on restart and all existing executors started working immediately) |
