Petr Miko reopened CXF-6427:
----------------------------

Please see previous comment - if received message is NOT inputStream, due to autoClose property set to false by default is not the Message.entity input stream closed - there should be *||* not *&* in checking condition.

> In current implementation of _org.apache.cxf.jaxrs.client.AbstractClient_ is response body input stream closed in following method
> {noformat}
>     protected boolean responseStreamCanBeClosed(Message outMessage, Class<?> cls) {
>         return cls != InputStream.class
>             && MessageUtils.isTrue(outMessage.getContextualProperty("response.stream.auto.close"));
>     } 
> {noformat}
> That means, that in case that if the _response.stream.auto.close_ is not set to true, the input stream stays opened -> Socket is not free for reusing. 
> In my opinion the proper implementation should be:
> {noformat}
>   protected boolean responseStreamCanBeClosed(Message outMessage, Class<?> cls) {
>     return !cls.isAssignableFrom(InputStream.class) || MessageUtils.isTrue(outMessage.getContextualProperty("response.stream.auto.close"));
>   }
> {noformat}  
> This way is the response body input stream:
> * is closed even when the auto close property is not set (= default?) and cls is not a child of InputStream
> * the input stream is not closed, if cls is child of InputStream class (do not know if there might be cases of its subclasses) and the auto close property is not set to true
> * the auto close property still can over-rule the fact that the cls is assignable from InputStream
> The current implementation is in my opinion incorrect, because in case of a lot quick/parallel requests over proxy clients we faced running out of Sockets - similarly to what is described in CXF-5144
