env: java1.8 tomcat-apache-tomcat-8.0.29 ssm 4.1.4+-

I've met a dead loop caused by this class ResponseWrapper.java @Override public ServletResponse getResponse() { return this; } when run the application on tomcat, an error appeared by request the web.html in the application see these codes from DefaultServlet.java:895 ServletResponse r = response; long contentWritten = 0; while (r instanceof ServletResponseWrapper) { r = ((ServletResponseWrapper) r).getResponse(); } The ResponseWrapper.getResponse() method will return the Object itself forever. cause the dead loop. suggest @Override public ServletResponse getResponse() { return super.getResponse(); }
