Saisimon opened a new issue #2604: The query entity throws an exception when a boolean property exists in the entity URL: https://github.com/apache/incubator-shardingsphere/issues/2604 ## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/incubator-shardingsphere-example/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response **more than 7 days** and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? 4.0.0-RC2-SNAPSHOT，4.0.0-RC1 version work well ### Which project did you use? Sharding-JDBC or Sharding-Proxy? Sharding-JDBC ### Expected behavior Work well ### Actual behavior throw java.lang.ClassCastException: [B cannot be cast to java.lang.Boolean ### Reason analyze (If you can) MySQL column type is BIT, MergeResultSet value is an byte array, can not convert to boolean. ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. pom.xml ```xml
