Bug ID: 65272
Summary: Problems proccessing HTTP request without CR in last
versions
Product: Tomcat 9
Version: 9.0.x
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Connectors
Assignee: dev@tomcat.apache.org
Reporter: miguelinh...@gmail.com
Target Milestone: -----
With last versions of Apache Tomcat 9, we have problems to process http request
created by legacy systems that haven't <CR> separating the sections of a HTTP
Request, having only a LF as delimeter.
The error returned by Tomcat is:
java.lang.IllegalArgumentException: Invalid character found in the HTTP
protocol [HTTP/1.00x0aUser-Agent:]
at
org.apache.coyote.http11.Http11InputBuffer.parseRequestLine(Http11InputBuffer.java:559)
at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:261)
This request fails in Apache Tomcat 9.0.45, 9.0.41 but works in Apache Tomcat
9.0.26 or in Apache Tomcat 7.

You can test this using this java code (supossing tha Tomcat is running on 8080
port at localhost):
The mensaje2 variable works fine (CRLF is represented by 13,10 codes).
The mensaje2 fails (LF is represented by 10 code)
int[] mensaje2 =
