What is the exact meaning of the field "badConnectionCount" of PoolState?

[js.kim]

Hi, I have an application server and using mybatis 3.0.5 to connect to
MySql DB.
It works well but someday I found that the field "badConnectionCount"
of PoolState was not zero.
Is it means that some connections in a mybatis connection pool are
invalid and they just hold DB connection resources?

thanks for reading

No. It means that there has been invalid conections that have been
closed (if possible) and discarded.
