generic classpath arguments cannot be passed to execution

[GoogleCodeExporter]

What steps will reproduce the problem?
1. try to instantiate a class using reflection, that exists in a jar that was 
added to classpath from command line using -cp

2. exception. class is not found in classpath

What is the expected output? What do you see instead?
class in jar that was added to classpath is found

What version of onejar-maven-plugin are you using?
0.97

What is the output of "mvn -version" on your machine?
1.7 64bit

Please provide any additional information below.
running the jar with java -jar ignores classpath arguments
and running the jar with java -classpath + main class throws err cant find main
these issues have to do with the plugin classloader
so generic classpath arguments cannot be passed to execution
