David Li commented on ARROW-9448:
---------------------------------
Adding a test like this is enough
{code:java}
@Test
public void testZeroBuf() {
allocator.getEmpty().print(new StringBuilder(), 0,
BaseAllocator.Verbosity.LOG_WITH_STACKTRACE);
}
{code}
> [Java] Circular initialization between ArrowBuf and BaseAllocator leads to
> null HistoricalLog for empty buffer
> --------------------------------------------------------------------------------------------------------------

> Key: ARROW-9448
> URL: https://issues.apache.org/jira/browse/ARROW-9448
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java
> Affects Versions: 1.0.0
> Reporter: David Li
> Priority: Blocker
>
> 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
