Stefania commented on CASSANDRA-11973:
--------------------------------------
bq. [~philipthompson]: would it be possible to run the offheap dtests at least
with one of these patches?
Actually, leave it, it's easier if I change the settings manually myself, so
I'll take care of this.
> Is MemoryUtil.getShort() supposed to return a sign-extended or
> non-sign-extended value?

> In org.apache.cassandra.utils.memory.MemoryUtil.getShort(), the returned
> value of unsafe.getShort(address) is bit-wise-AND'ed with 0xffff, while that
> of getShortByByte(address) is not. This inconsistency results in different
> returned values when the short integer is negative. Which is preferred
> behavior? Looking at NativeClustering and NativeCellTest, it seems like
> non-sign-extension is assumed.
> By the way, is there any reason MemoryUtil.getShort() and
> MemoryUtil.getShortByByte() return "int", not "short"?
