Add more mutex to wherever JDStates is used to avoid data race problem.

Note all the public interface already locks the mutex and the functions changed here are only used within the public interface. So, the lock would be redundant.

If there is some case I missed, please let me know.

Okay, good to know that.

I just think that since it is a recursive_mutex, we just need to lock it whenever we use it to avoid the mental burden of remembering to lock it in the public interface.
