when use java-client version: 2.5.0, the server is ok! but update nebula-jdbc, use java-client: 2.6.2, it print error info: com.vesoft.nebula.client.graph.exception.NotValidConnectionException: No extra connection: All servers are broken. at com.vesoft.nebula.client.graph.net.NebulaPool.getConnection(NebulaPool.java:215) at com.vesoft.nebula.client.graph.net.NebulaPool.getSession(NebulaPool.java:137)

3q, it's the version mismatch problem, the graph version is 2.5.1. the error is miss when graph upgrade to 2.6.2.
