Hm, interesting, it looks like the test had not only flakiness issue..
In JDK8 the capacity value was stored in java.nio.Bits in a "long" field,
since Java 11 the value is in "AtomicLong" but we tried to get it as long using
"BITS_TOTAL_CAPACITY.getLong(null)" before CASSANDRA-19022..
so, before CASSANDRA-19022 we actually get always "-1" as a value for the
column and the logic to check direct byte buffer usage actually did not work..
