I think some of the performance benchmarks might be configured incorrectly. A few Java benchmarks use `Level.Invocation` when setting up and tearing down, including WriteChannelBenchmark: https://github.com/apache/arrow/blob/2146ab10e653f927a6e92d29ee0910f30f4cb996/java/performance/src/test/java/org/apache/arrow/vector/ipc/WriteChannelBenchmark.java#L58-L69 According to the javadocs, `Level.Invocation` has dragons: https://javadoc.io/static/org.openjdk.jmh/jmh-core/1.1.1/org/openjdk/jmh/annotations/Level.html#Invocation `Level.Invocation` is only for benchmarks that take >=1ms. Our benchmark is zeroing out an unaligned 8 byte buffer.. Running the benchmark shows billions of these buffer alignment operations in the benchmark, which makes me think there is some race condition happening on setup/teardown causing a near infinite loop. -- This is an automated message from the Apache Git Service.
