Hey,

I am trying to use the [j2mod](https://github.com/steveohara/j2mod) dependency in my urcap. I got the latest build form [maven repository](https://mvnrepository.com/artifact/com.ghgande/j2mod/3.0.0), and included the dependency in my pom.xml file.

Then, adding the artifact id to the `<Embed-Dependency>j2mod;scope=compile|runtime</Embed-Dependency>` tag in the maven bundle plugin, and exclude from the `<Import-Package> !com.ghgande.j2mod, com.ur.urcap.api*, *</Import-Package>` tag.

This cases polyscope to want jSerialComm, Slf4j-api, Slf4j-impl… and so on. It seems to be a never ending dependency tree. So far my pom looks like this.

```auto
<Embed-Dependency>j2mod, jSerialComm, slf4j-api, slf4j-log4j12, log4j-core ;scope=compile|runtime</Embed-Dependency>
						<Embed-Transitive>true</Embed-Transitive>
						<Import-Package>
							!com.ghgande.j2mod,
							com.ur.urcap.api*,
							*
						</Import-Package>
					</instructions>
				</configuration>
			</plugin>
			...
		</plugins>
	</build>

	<dependencies>
		<dependency>
