Description

Still working on a reproduction (this is internal code), but what I see is:

1. Test initializes a RootAllocator in a JUnit @Before
2. BaseAllocator.<clinit> creates a Config
3. The constructor of ImmutableConfig gets the allocation manager
4. This eventually runs NettyAllocationManager.<clinit>
5. This creates a static ArrowBuf as the empty buffer
6. The ArrowBuf has a null HistoricalLog as BaseAllocator hasn't fully initialized yet
