After starting the karaf console and attempting to `features:install webconsole`, I get the following error:
karaf@root> features:install webconsole
Error executing command: URL [mvn:org.apache.felix/org.apache.felix.metatype/1.0.4] could not be resolved.
The machine I am executing this command on is on the same network with the same http proxy as my local running machine with Windows 7 x86_64. The karaf binary for Windows does not suffer from the same problem. I have configured etc/system.properties with http.proxyHost and http.proxyPort on both machines.
