About the issue of lock downgrade

[zhuo chen]

Dear All

Please help me, I have a question, from this article
http://openjdk.java.net/jeps/8183909. Why is the weight lock here
downgraded to lightweight, is there any benefit to doing this? Why not
directly downgrade to a bias lock? Thank you for answering my question.Very
looking forward to reply.

 Thank you guys
