CPU:total 1 (initial active 1)
Can easily be verified by using rr [1] which sets _SC_NPROCESSORS_ONLN and _SC_NPROCESSORS_CONF to 1 [2]:
rr java -XX:+UseNUMA --version
Also fails with:
rr java -XX:+UnlockExperimentalVMOptions -XX:+UseZGC --version
The _cpu_to_node GrowableArray has length 1 since the processor count is 1 (set at [3]). It then crashes at [4] because the index is 0*BitsPerCLong + 1 = 1 but the array has only length 1.
