Spring microservice encounters infinite loop when calling readLongs method resulting in denied access.

Describe the bug
A clear and concise description of what the bug is.
While using Spring microservices, I utilized the 【com.esotericsoftware.kryo.unsafe.UnsafeInput.readLongs()】 method, but encountered an infinite loop, resulting in denied access to the microservice. I have written a POC here that you can use to reproduce the issue. Could you please take a look and let me know your thoughts? Thank you very much.
Please let me know if you need any clarification or have additional details to add about the issue you encountered. I'm happy to assist further.

To Reproduce
Provide a minimal reproducible example of the problem, ideally in the form of a runnable test-case.
public void main() {
UnsafeInput unsafeInput = new UnsafeInput();
long[] result = unsafeInput.readLongs(20);
}

Environment:

• OS: [e.g. windows10]
• JDK Version: [e.g. 11]
• Kryo Version: [e.g. 5.5.0]
  
  com.esotericsoftware
  kryo
  5.5.0
  

Additional context
Add any other context about the problem here.

The infinite loop occurs in the while loop of the com.esotericsoftware.kryo.unsafe.UnsafeInput.readBytes method

I think your test-case is too minimal. You cannot use UnsafeInput without a buffer:

/** Creates an uninitialized Input, {@link #setBuffer(byte[])} must be called before the Input is used. */
public UnsafeInput () {
}

Can you create a reproducer that uses a valid input?
