[CXF-8272] getting IOException: stream is closed after calling @Oneway SAP-Service

Description

At first: I'm not sure if this is a CXF issue or a infrastructure problem in the customer-environment.

Currently wa have an APP_SERVER_OLD that calls services from SAP_SERVER without issues.
Now we moved from APP_SERVER_OLD to APP_SERVER_NEW but still using SAP_SERVER:

On APP_SERVER_NEW we have the problem, that after an async-Soap-Service-call (method has @Oneway-annotation) we get an IOException: stream is closed during closing of the the InputStream.

Calling non-@Oneway services works as expected on APP_SERVER_NEW.

Currently I assume that this is a infrastructure-problem because we are using the same software-version on APP_SERVER_OLD and APP_SERVER_NEW.
Unfortunately I don't have a testcase.

Does anyone know why this can happen?
Or is this maybe a bug in CXF?
Here is the relevant part of the stacktrace:

As you can see this error occurs because IOUtils.consume is called during close thile the stream is already closed.

I know that 2.7.18 is an old version but this can also happen in current versions:

https://github.com/apache/cxf/blob/master/rt/transports/http/src/main/java/org/apache/cxf/transport/http/URLConnectionHTTPConduit.java

Maybe you can check if the stream is already closed?

Is there something we can do to prevent this error?
