> Connection Leak in HttpClientWrappedOutputStream due to Unreleased Resources
> on IOException
> -------------------------------------------------------------------------------------------

> Key: CXF-9095
> URL: https://issues.apache.org/jira/browse/CXF-9095
> Project: CXF
> Issue Type: Bug
> Components: Transports
> Affects Versions: 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.5, 4.0.6
> Environment: - Apache CXF Version: 4.0.6
> - Java Version: OpenJDK 17.0.12
> - Operating System: Ubuntu 18.04 AMD 64
> Reporter: suxuan
> Priority: Major
>
> When the `close` method of the parent class
> `org.apache.cxf.transport.http.HTTPConduit.WrappedOutputStream` is called, a
> timeout occurs at line 1420, resulting in an `IOException`. This exception is
> caught at line 1428 and subsequently rethrown to the upper layer.
> The upper layer, specifically the `close` method in
> `org.apache.cxf.transport.http.HttpClientHTTPConduit.HttpClientWrappedOutputStream`,
> does not properly handle the exception. As a result, the `pout` resource
> (which corresponds to the socket for writing) is not released, leading to a
> connection leak.
> *{color:red}The Java exception stack trace is as follows{color}*:
> Caused by: java.net.http.HttpTimeoutException: HttpTimeoutException invoking
