After the response is committed, following API throws IllegalStateException. It's O.K. but the message of the exception is not set. - HttpServletResponse#resetBuffer - HttpServletResponse#sendError - HttpServletResponse#sendRedirect - HttpServletResponse#setBufferSize To understand the bug of the application, it is hoped that the message is set like other exceptions.
If you tell us what message you want to see, I'll be glad to add them.
I think that's enough if they are same as the messages used with org.apache.catalina.connector.Response. LocalStrings(_xx).properties: coyoteResponse.resetBuffer.ise coyoteResponse.sendError.ise coyoteResponse.sendRedirect.ise coyoteResponse.setBufferSize.ise Regards.
Fixed in 7.0.x for 7.0.20. I do not intend to propose this for back-port.
