Error in Accept-Encoding header in jdk 1.8.0_91

Question

I am making a POST call. The call is working on one system (say system1) and not working on the other system (say system2).

I am getting following error:

Header

I am sending following header on both systems: Accept-Encoding: gzip, deflate, br

Java versions system1:

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

system2:

openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

I also tried to check the source code where the error is thrown (check code of checkMessageHeader method):

dk8-b91: http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/169451cf0cc5/src/share/classes/sun/net/www/protocol/http/HttpURLConnection.java

jdk8-b51: http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/e865efbc7105/src/share/classes/sun/net/www/protocol/http/HttpURLConnection.java

In both the files the source code for checkMessageHeader is identical. Also source code is checking for \n and throwing error after checking some conditions, but only if \n is present. I don't have any \n in the key or value.

I am not able to understand what could be the issue? Or how to proceed?

Answer 1

Got the solution for my case. The ':' character is creating the issue (at least in my case).

If I do the following:

headers.put("Authorization",Collections.singletonList("Bearer 123"));

It is ok.

So, I think in the original problem of this thread, instead of providing the key as "Accept-Encoding:" if "Accept-Encoding" is provided, the probably that may work.

Chrees!
