• Ensure that 'com.kingbase8.core.BaseConnection' is the correct parameter type expected by Kingbase XA connections. If the actual connection type is 'com.kingbase8.jdbc.KbConnection' or a subclass thereof, this mismatch could lead to runtime reflection errors.

Class<?> kingbaseConnectionClass = Class.forName("com.kingbase8.core.BaseConnection");

The driver scope of Kingbase is test, which is not included in the released binary, so I think it should comply with ASF regulations.
