Using ${artifcactId}-Extention-Name in MANIFEST file can create invalid MANIFEST files

If you have a maven dependency on an something with an artifactId that contains a '.' in it, it creates an illegal manifest file when trying to create an executable jar file (java -jar foo.jar).

Exception in thread "main" java.io.IOException: invalid header field name: geronimo-jms_1.1_spec-Extension-Name
        at java.util.jar.Attributes.read(Attributes.java:409)
        at java.util.jar.Manifest.read(Manifest.java:167)
        at java.util.jar.Manifest.<init>(Manifest.java:52)
        at java.util.jar.JarFile.getManifestFromReference(JarFile.java:158)
        at java.util.jar.JarFile.getManifest(JarFile.java:145)

Here's my configuration:

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <configuration>
          <archive>
            <manifest>
              <mainClass>my.class.Test</mainClass>
              <addClasspath>true</addClasspath>
              <addExtensions>true</addExtensions>
              <classpathPrefix>./lib/</classpathPrefix>
            </manifest>
          </archive>
        </configuration>
      </plugin>

I added the following dependency:

    <dependency>
      <groupId>org.apache.geronimo.specs</groupId>
      <artifactId>geronimo-jms_1.1_spec</artifactId>
    </dependency>

When the maven-archiver tries to create a manifest file with the JARs dependencies it adds the following to the META-INF/MANIFEST.MF file:

geronimo-jms_1.1_spec-Extension-Name: geronimo-jms_1.1_spec
geronimo-jms_1.1_spec-Implementation-Version: 1.0

After digging around a bit it turns out that '.' is an illegal character in the "Extension-Name" and "Implementaion-Version" header fields, which leads to the following exception when I try to run "java -jar Test.jar"

java.io.IOException: invalid header field name: geronimo-jms_1.1_spec-Extension-Name
