Yes, the vast majority of Java objects (with the exception of Object
arrays) are smaller than 128 bits and thus fit within our 30-bit marking
descriptor [*]. Even then, we can still handle larger objects provided
that all their reference fields fit within the bitmap (as is the case
for Strings and primitive arrays).
