> Axis2 does not properly return http connection to connection pool when using

>
> Key: AXIS2-5809
> URL: https://issues.apache.org/jira/browse/AXIS2-5809
> Project: Axis2
> Issue Type: Bug
> Components: transports
> Affects Versions: 1.7.3
> Environment: Ubuntu 16.04, OpenJDK 7
> Reporter: Christian H.
> Priority: Critical
>
> When using HTTP Client 4 with a generated WSDL-Client the HTTP connections
> are not returned properly to underlying connection pool. The HTTP connections
> are still allocated, when new requests are made. This ends up in waiting for
> HTTP connections from pool, but no connections are available anymore.
> The connections should be returned to pool as stated in the Apache HTTP
> Client 4 documentation (2.3.1):
> https://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html
> Here is some example code to reproduce the problem. The BLZServiceStub is a
> generated WSDL client (wsdl2java) of the following service:
> http://www.thomas-bayer.com/axis2/services/BLZService?wsdl . But the problem
> is independent of the used service.
