Iwan Aucamp created HTTPCLIENT-1558:
---------------------------------------
Summary: Problematic OSGi bundling
Key: HTTPCLIENT-1558
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1558
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 4.3.5
Environment: Linux, Karaf
Reporter: Iwan Aucamp
org.apache.httpcomponents:httpclient-osgi:4.3.5 includes some class files from
org.apache.httpcomponents:httpcore-osgi:4.3.2 and also exports the same
packages. This causes some problems for karaf (and presumably other OSGi
containers).

Error executing command: Uses constraint violation. Unable to resolve bundle
revision org.apache.httpcomponents.httpclient [57.1] because it is exposed to
package 'org.apache.http.io' from bundle revisions
org.apache.httpcomponents.httpcore [56.1] and
org.apache.httpcomponents.httpcore [56.0] via two dependency chains.
Chain 1:
org.apache.httpcomponents.httpclient [57.1]
import:
(&(osgi.wiring.package=org.apache.http.io)(version>=4.3.0)(!(version>=4.4.0)))
|
export: osgi.wiring.package=org.apache.http.io
org.apache.httpcomponents.httpcore [56.1]
Chain 2:
org.apache.httpcomponents.httpclient [57.1]
import:
(&(osgi.wiring.package=org.apache.http.impl.entity)(version>=4.3.0)(!(version>=4.4.0)))
