Research direction

Start with com.alibaba.otter.node.etl.select.selector.MessageParser, especially the parse and internParse locations in the stack trace, then inspect com.alibaba.otter.shared.etl.model.EventType for XACOMMIT handling. Reproduce the synchronization failure with the reported event and determine what behavior is expected; done means the event is processed without this exception.
