> Still working on a reproduction (this is internal code), but what I see is:
> # Test initializes a RootAllocator in a JUnit @Before
> # BaseAllocator.<clinit> creates a Config
> # The constructor of ImmutableConfig gets the allocation manager
> # This eventually runs NettyAllocationManager.<clinit>
> # This creates a static ArrowBuf as the empty buffer
> # The ArrowBuf has a null HistoricalLog as BaseAllocator hasn't fully
> initialized yet
