Tekrar ediyorum, bu VM bağımlıdır, ama benim Windows dizüstü Güneş ile İLGİLENİYORUZ çalışan aşağıdaki sonuçları aldım 1.6.0_11 inşa:

Size for LotsOfBooleans: 87978576
Average size: 87.978576
Size for LotsOfInts: 328000000
Average size: 328.0

Bu mantıksal temelde Sun'ın JVM tarafından bir bayt her içine paketlenmiş olabilir düşündürmektedir.
