Robert Muir commented on LUCENE-6239:
-------------------------------------

In any case, Unsafe is not used here to modify anything so there is nothing
that can crush, we dont write bytes to non-aligned positions like Netty does
and fails on Sparc. We just call some methods to retrieve some values from the
JVM internal - there is no risk (it just may fail to get the value).

We don't even need to debate this. This is absurdly risky. Just look at the
conversation you are having. We don't need this in a search engine library.

> We are a search engine, not a ram calculator.
