Hi, Mr.Cemper ! This problem has been solved with the help of my workmate. We print the logs on the catch codeblock belongs to method that parsing XML messages and find out that all the messages sent to this method include <?xml version="1.0"> tag extraly.Lastly we solved this problem by replace the tag with blank. Thank you again!
Thank you for your professional answer！But I have still no idea that how to locate the messages that caused this error , this BS is deployed on production environment so that messages sent by callers can not be located. Can you plz tell me how to find them out? (such as by printing the logs on somewhere or other way
