>             Project: Camel
>          Issue Type: Bug
>          Components: camel-http
>    Affects Versions: 2.12.4
>         Environment: IBM Websphere Liberty Core 17.0.0.1
> IBM Websphere Liberty Core 17.0.0.2
> Reproducible using both IBM JDK 8 and Oracle JDK 8
>            Reporter: Zeljko Vukovic

>            Priority: Minor

> Dear Camel team,
> While working on one integration we found issue related to camel-http component when solution is deployed on IBM Liberty core.
> Same issue is not reproducible on Jetty and Tomcat.
> Issue is connected to the code in IOHelper and CachedOutputStream$WrappedInputStream
> We are using version 2.12.4 but I can see that same code is used also in latest versions.
> https://github.com/apache/camel/blob/camel-2.12.4/camel-core/src/main/java/org/apache/camel/util/IOHelper.java
> Problematic part are lines 196, 198 and 204.
> Basically stream reader which is used org.apache.camel.converter.stream.CachedOutputStream$WrappedInputStream is not returning -1 like response of read method if empty string is provided on input.
> This is wrong by specification of InputReader interface.
>        // in the case there is input which is empty string
>        while ( -1 != n) {
>          …
>          int n = input.read(buffer);  ---> this is never -1 if string is empty "" already 0 and we have infinitive loop !!!
>         }
>  
> For our use case we have applied change in IOHelper to check and directly cover if stream reader produce same (non-valid) response to not produce infinitive loop.
> If any questions around reproducing issue please let me know
> Best regards,
> Zeljko
