			.withLongCompressed(true)

Would it possible be some memory alignment issue in JDK unsafe?

Would it possible be some memory alignment issue in JDK unsafe?

I was able to serialize successfully using the default serialization tool in JDK, but when I encountered problems using Fory, I simply called the 'serialize' method, and I'm not sure if it's a compatibility issue with the operating system?

We don't support Arch Linux aarch64 yet, I guess it's Unsafe memory operation unaligned issue
