Apparently, httpcomponents-client does not require org.apache.log or org.apache.avalon.framework: https://issues.apache.org/jira/browse/HTTPCLIENT-1082 Yet, there are Import-Package: org.apache.log, org.apache.avalon.framework in httpcomponents-client's MANIFEST.MF. I'm not sure why that is.
I assume this has been fixed by your commit 0f67941. Closing as fixed since avalon-framework is now in: Ignore-Package: org.apache.log,org.apache.log4j,org.apache.avalon.fram ework.logger
You are right. Thanks, Stanislav.
