我正在使用WSO2SP版本4.3.0]和regex扩展名：siddhi-execution-regex-4.1.2.jar。我的代码工作正常，但是每当我重新启动wso2sp实例时，我都会开始收到错误消息“ 在siddhi文本输入映射器的流transactionstream1中将文本消息转换为Siddhi事件时发生异常。java.lang.StackOverflowError”我必须多次重启wso2sp才能使它正常工作，这不是可行的解决方案。我还使用扩展名siddhi-io-http-1.0.40.jar通过http发送文本消息。文字地图扩展名：siddhi-map-text-1.1.2.jar和siddhi-map-text-1.0.22.jar
