Real bucket layout of a 6-entry HashMap<String,Integer> (default capacity)
==========================================================================

map.size() = 6
table.length = 16 | non-empty buckets = 4
  bucket[  0]  chain=2    kind=Node
  bucket[  1]  chain=2    kind=Node
  bucket[  4]  chain=1    kind=Node
  bucket[  5]  chain=1    kind=Node

Index for each key, computed the same way HashMap.hash() does it:
  apple    hashCode=93029210     spread=93030097     index=(16-1)&spread=1
  banana   hashCode=-1396355227  spread=-1396317280  index=(16-1)&spread=0
  cherry   hashCode=-1361513063  spread=-1361552575  index=(16-1)&spread=1
  date     hashCode=3076014      spread=3075968      index=(16-1)&spread=0
  egg      hashCode=100357       spread=100356       index=(16-1)&spread=4
  fig      hashCode=101380       spread=101381       index=(16-1)&spread=5
