connection-pool settings occured something wrong? Network is not wrong.(Other java native client is correct moving.)

■my settings

■error message.

2015y11m30d_171045989.jpg

■ApplicationLog:

2015-11-30 16:11:18.328+0900 [L: ERROR] [O: c.t.w.BaseService] [I: ] [U: Administrator] [S: ] [T: http-nio-80-exec-7] [context: com.thingworx.webservices.context.HttpExecutionContext@11123240][message: Unable to Invoke Service SelectData on hiveConnection : Cannot get a connection, pool error Unable to validate object]

・ "Cannot get a connection, pool error Unable to validate object"

-> "connectionValidationString" is wrong?

i tried to enter "select now()" and "select 1" and "select * from dual" ,

but still give same error.
