URL: https://github.com/apache/shardingsphere/issues/8570
## Question
There is a new property `exceptionOverrideClassName` in HikariCP 3.4.3. If
the method `setExceptionOverrideClassName` was invoked with `null` value, NPE
will occurred.
```yaml
[zk: zk36.zk.svc.cluster.local:2181(CONNECTED) 2] get
/shardingsphere-governance/schemas/logic_db/datasource
dataSources:
dataSource:
dataSourceClassName: com.zaxxer.hikari.HikariDataSource
props:
password: postgres
transactionIsolation: null
connectionTestQuery: null
driverClassName: org.postgresql.Driver
jdbcUrl: jdbc:postgresql://pg.local.wwj.icu:5432/elasticjob
schema: null
dataSourceClassName: null
connectionTimeout: 30000
idleTimeout: 600000
exceptionOverrideClassName: null
username: postgres
dataSourceJNDI: null
initializationFailTimeout: 1
minimumIdle: 10
maxLifetime: 1800000
maximumPoolSize: 10
validationTimeout: 5000
leakDetectionThreshold: 0
connectionInitSql: null
poolName: HikariPool-1
catalog: null
```
```java
GovernanceCenterConfiguration centerConfiguration =
getGovernanceCenterConfiguration();
GovernanceConfiguration governanceConfiguration = new
GovernanceConfiguration("shardingsphere-governance", centerConfiguration, true);
DataSource dataSource =
GovernanceShardingSphereDataSourceFactory.createDataSource(governanceConfiguration);
```
```
