Short description of the issue/suggestion:

Error: Could not find or load main class com.kerner1000.myapp.Launcher
Caused by: java.lang.ClassNotFoundException: com.kerner1000.myapp.Launcher

My Info.plist looks like this:

    <key>JavaX</key>
    <dict>
        <key>MainClass</key>
        <string>com.kerner1000.myapp.Launcher</string>
        <key>ClassPath</key>
        <array>
            <string>Java/myapp-0.6.4-SNAPSHOT.jar</string>

        <key>RelocateJar</key>
        <true/>
    </dict>

MANIFEST.MF inside the jar:
