具有关闭连接的BoneCp池

Question

我正在使用slick的Bonecp数据源。并发现池中包含关闭的连接，因此我总是会遇到此异常

配置：

datasource {
  driver-class = "com.mysql.jdbc.Driver"
  partition-count = 2
  min-connections-per-partition = 8
  max-connections-per-partition = 16
  connection-timeout = 5s
  connection-test-statement = "select 1"
  query-execute-time-for-log = 2s
  default-auto-commit = true
  acquire-increment = 1
  acquire-retry-attempts = 10
  acquire-retry-delay = 1s
  idle-max-age = 10minutes
  max-connection-age = 1h
}

有人能告诉我bonecp或我的配置出了什么问题吗？

我发现最新的BoneCP版本有一个或多个与关闭连接相关的错误，并且我遇到了类似的异常。请尝试升级到BoneCP的最新快照。
