Major Description
Karaf 4.1.1 installs asm 6 which is used by aries proxy and xbean finder .. among others.
As dependency="true" is set for asm it is replaced if a feature requires a different version. In this case all bundles requiring asm are refreshed. As aries proxy 1.1.0 is only one bundle the refreshs are cascaded up until shell.core which causes this behaviour:

This happens for example if the http feature or activemq feature is installed.
A solution is to remove dependency=true on asm which then causes two asm versions to be installed and no refreshs to happen.
