I got the following assert when running a hotspot push job to jdk10/hs:

# Internal Error (/scratch/opt/jprt/T/P1/165928.mikael/s/hotspot/src/share/vm/utilities/hashtable.cpp:339), pid=4554, tid=4584
# assert(max_bucket_count < ((1 + number_of_entries()/table_size())*10)) failed: Table is unbalanced

Specifically, this was running the linux_x64_3.8-fastdebug-c2-hotspot_tier1_gc_2 tests, and seemed to crash when running the TestNewRatioFlag$NewRatioVerifier test.
