assert(InstanceKlass::cast(k)->is_initialized()) failed: need to increase java_thread_min_stack_allowed calculation

I saw this just once, on arm, during testing of a clean JDK10 repo:

# Internal Error (/scratch/opt/jprt/T/P1/215921.cplummer/s/hotspot/src/share/vm/utilities/exceptions.cpp:230), pid=72834, tid=72835
# assert(InstanceKlass::cast(k)->is_initialized()) failed: need to increase java_thread_min_stack_allowed calculation
