Some of Nashorn subbenchmarks can suffer a lot when an uncommon trap w/ Reason_speculate_class_check sometimes settles with Action_none after too many traps occured. It causes continuous deoptimizations and performance regresses a lot (up to 50x).
ILW = HLH = P2
I = H: severe performance regression on Nashorn
L = L: requires very specific race between nmethod deoptimizations and recompilation; Nashorn & other JSR292 users are affected
W = H: none
