jimmycheng888 opened a new issue #2302: ShardingPreparedStatement Class exception not caught URL: https://github.com/apache/incubator-shardingsphere/issues/2302 **Which version of ShardingSphere did you use?** 3.1.0 **Which project did you use? Sharding-JDBC or Sharding-Proxy?** Sharding-JDBC `Actual behavior` The code exception is not caught, causing a null pointer exception, and does not throw a true exception, making it impossible for the developer to accurately determine what went wrong. **Example codes for reproduce this issue (such as a github link).** The code packge is : io.shardingsphere.shardingjdbc.jdbc.core.statement For example, the following code, the special symbol will be a direct null pointer, and the real reason is not exposed. ``` @Override public boolean execute() throws SQLException { try { clearPrevious(); sqlRoute(); initPreparedStatementExecutor(); return preparedStatementExecutor.execute(); } finally { refreshTableMetaData(connection.getShardingContext(), routeResult.getSqlStatement()); clearBatch(); } } ```
