Most of the time, the crash happens when a client reconnects to their active session where a JVM is already running. On reconnect, the list of printers is synced with the local printers on the client. In such a scenario, other software could also update its list of printers as well as repaint its UI. If the system is under high load, it's not impossible to have a long enough pause between the calls.
