java - Header parse error after upgrade to Jetty 9.3 -


i'm having issue when change jetty distro 9.2 9.3. under 9.2 app works flawlessly when running same war file , connecting same client following error messages when running under 9.3:

015-08-30 14:55:32.174:warn:oejh.httpparser:qtp1100439041-12: illegal character 0x20 in state=header_in_name buffer heapbytebuffer@26dab36[p=62,l=654,c=8192,r=592]={post /api/v1/time...0.1:8080\r\nkey <<<info header: ...erica/toronto"}>>>\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00...\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00}

2015-08-30 14:55:32.175:warn:oejh.httpparser:qtp1100439041-12: bad http parsed: 400 illegal character 0x20 httpchanneloverhttp@6765bf81{r=0,c=false,a=idle,uri=-}

from understand, there illegal character in header, why 1 version throw error , other not?

also using apache httpclient 4.4.1 send data.

the upgrade jetty 9.2 9.3 meant entered in new world of http/1.1 updated specs , rfcs, , new http/2 requirements, including changes http/1.1 support http/2 upgrade (h2c).

jetty 9.2 followed rfc2616 (now obsoleted by: rfc7230, rfc7231, rfc7232, rfc7233, rfc7234, rfc7235 , updated by: rfc2817, rfc5785, rfc6266, rfc6585)

jetty 9.3 follows updates venerable (from 1999!) rfc2616 spec. many things valid in past no longer valid. dropped support http/0.9 in jetty 9.3

there many parts of http/1.1 tidied take advantage of updated rfcs, of them might have bit you.

looking @ spec, rfc7230: section 3.2 - header fields, see header field declared as...

 header-field   = field-name ":" ows field-value ows   field-name     = token  field-value    = *( field-content / obs-fold )  field-content  = field-vchar [ 1*( sp / htab ) field-vchar ]  field-vchar    = vchar / obs-text   obs-fold       = crlf 1*( sp / htab )                 ; obsolete line folding                 ; see section 3.2.4

with token defined in rfc7230: appendix b - collected abnf ...

tchar = "!" / "#" / "$" / "%" / "&" / "'" / "*" / "+" / "-" / "." /         "^" / "_" / "`" / "|" / "~" / digit / alpha token = 1*tchar

which means " " (space) in "info header:" invalid per spec.

it better if "info-header" or more accurately following spec "x-info-header" (so not conflict spec reserved header names)

incidentally, space in header name valid in http/0.9 (not anymore).
