I have found a work-around for my case. The original code of my servlet was like this:
ObjectMapper mapper = new ObjectMapper(); // Jackson Mapper mapper.readValue(request.getInputStream(), "utf-8") I have added a buffer to hold all the request: byte[] content = readFully(request.getInputStream()); mapper.readValue(content, "utf-8") Now the error has disappeared. I have not checked the code of Jackson Mapper. Is is possible that the ChunkedInputFilter breaks in case of reading more times after the end of the stream ? (calling ServletInputStream#read more times after -1 marker) Should I file an issue ? I'm really sorry but today I have not time to create a working JUnit testcase to demostrate the issue. I can work on it next days. -- Enrico 2017-01-09 16:31 GMT+01:00 Enrico Olivelli <eolive...@gmail.com>: > Hi, I am upgrading from Tomcat 8.0.33 to 8.5.9. > I have the following error during a POST made with Apache-HttpClient 4.3.6 > > I this this is the bad "POST" > > FINE Jan 09, 2017 3:45:15 PM org.apache.coyote.http11.Http11InputBuffer > parseRequestLine > BUONO: Received [POST /majordodo HTTP/1.1 > Transfer-Encoding: chunked > Content-Type: application/json;charset=utf-8 > Host: sviluppo06-cs7.sviluppo.dna:11986 > Connection: Keep-Alive > User-Agent: Apache-HttpClient/4.3.6 (java 1.5) > Accept-Encoding: gzip,deflate > Authorization: Basic bWFnbmV3czptYWduZXdz > > 10b78 > ] > > > this is the stack trace of the error: > java.io.IOException: Invalid end of line sequence (character other than CR > or LF found) > at org.apache.coyote.http11.filters.ChunkedInputFilter. > throwIOException(ChunkedInputFilter.java:655) > at org.apache.coyote.http11.filters.ChunkedInputFilter. > parseCRLF(ChunkedInputFilter.java:475) > at org.apache.coyote.http11.filters.ChunkedInputFilter. > doRead(ChunkedInputFilter.java:262) > at org.apache.coyote.http11.Http11InputBuffer.doRead( > Http11InputBuffer.java:256) > at org.apache.coyote.Request.doRead(Request.java:540) > at org.apache.catalina.connector.InputBuffer.realReadBytes( > InputBuffer.java:319) > at org.apache.catalina.connector.InputBuffer.checkByteBufferEof( > InputBuffer.java:627) > at org.apache.catalina.connector.InputBuffer.read(InputBuffer. > java:342) > at org.apache.catalina.connector.CoyoteInputStream.read( > CoyoteInputStream.java:183) > > > Is it a client error on 'chunked' encoding format or is there some change > on Tomcat code which processes his kind of encoding ? > > I think that the client is sending a broken request, but before the > upgrade I did not get the error, is it possible ? > > I'm using Nio (not Nio2) http Connector, I'm going to to try Nio2 > > Thank you > Enrico Olivelli > > ..... >
