webstart-maven-plugin jarsigner fails with invalid SHA1 signature file digest

Question

I have been struggling to make webstart-maven-plugin work with a real certificate. I definitively need help.

Everything was working nice while I was self-signing the JNLP jar. To get rid of the Oracle's security alert while starting the app, we've bought a certificate. (By the way, it is expensive!)

I configured the keystone and changed the POM to sign my app with the new certificate and now I'm getting:

[info] jarsigner: java.lang.SecurityException: invalid SHA1 signature file digest for OSGI-OPT/src/org/osgi/framework/PackagePermission.java

The plugin configuration is:

        <plugin>
            <groupId>org.codehaus.mojo.webstart</groupId>
            <artifactId>webstart-maven-plugin</artifactId>

                    </keystoreConfig>
                </sign>

                <verbose>true</verbose>
            </configuration>
        </plugin>

When I run the "mvm clean package", it successfully sign lots of packages like log4j, javamail, my program itself, but when it tries to sign the org.osgi.core-4.0.0.jar it fails:

...

I spent hours googling and it seems that it has something to do with signing twice the jar or a pack200 bug. I would appreciate any help you could offer.

Tks

I solved this problem manually opening the problematic .jar and removing the manifest
