Jar hell in jagger distribution lib directory

[tanoshko]

Issue

Jagger distribution lib directory contains multiple versions of the same artifact.

Please see for recommendations #841

example:

tomcat:jasper-runtime:jar:5.5.12 -- excluding it fixes an issue
org.mortbay.jetty:jsp-2.1:jar:6.1.14

it results in kernel error:
