> BuddyAllocator always uses lazy allocation is mmap is enabled. If query
> fragment is interrupted at the time of arena allocation
> ClosedByInterruptionException is thrown. This exception artificially triggers
> allocator OutOfMemoryError and fails to notify other threads waiting to
> allocate arenas.
