If you throw an exception AND set the flag, usually the code in a catch block will behave weirdly because the catch code has not be written with that corner case in mind. Throwing an unrecoverable error usually avoid that problem (and yes, i'm aware it may clash with the way old executors work but virtual threads are our saviors). > > -Alan regards, Rémi
