As I was debugging the program and looking through the articles, I found that it would not release the HTTP Connection.

such as: https://stackoverflow.com/questions/26403674/apache-cxf-not-releasing-clients

Is there a solution to avoid this problem or release a new update to fix it?

https://issues.apache.org/jira/browse/CXF-8903 has been closed. There seems to be a workaround in cxf 4.0.3. apache/cxf@3d70de8
