Hi @KayWu, thank you for spotting and fixing this !

Can you please squash the two commits into one so I can merge the PR ?

Thanks in advance

Hi @ledoyen, I have squashed the two commits into one.
Thanks for reviewing.

[KayWu]

@ledoyen May I ask when is the next release?
I need to upgrade the lib once it releases.

[ledoyen]

@KayWu I just released a new version, it should be available in Maven Central within 2 hours.

Many thanks.
