@theoryxu it would be nice if you could add a UT for this feature, to demonstrate the behavior differences with this feature enabled/disabled.

@pan3793 Thank you for your review.

I‘ll figure out how Kyuubi's UT framework works and add one for this.

By the way, Are there other flaws I should know about? I could fix it at once.

@theoryxu I'm looking at the implementation in STS, which seems different, I suspect the behaviors are also different.
