You can use a pool , I used org.apache.commons.pool2 so the pool is responsible of providing connected sessions, basically:

• Create JSCH Session on makeObject
• connect on activate if disconnected
• check if isConnected on validate
• sendKeepAliveMsg on passivate

Above worked for me, also keep in mind that if you add logic on validate, the poolConfig should set true on testOnBorrow or testOnReturn. So I used KeyedObjectPool you should get connections from the pool via borrowObject method and make sure you return them to the pool once you operation is complete via returnObject.
