I tried to reason about this as well. The common reason to get here should be that we are hitting JVM limits on metaspace, not because of native memory exhaustion. It seems unlikely that we would even manage to get to this point if the system resources are so constrained that a buffer cannot be allocated. (We run a whole GC cycle before throwing the OOME).
