I finally found a "clean fix": in my Netbeans project/properties/libraries, I removed the "Filesystems API 8.0 Compatibility" and "Execution API 8.Compatibility" modules from the Platform cluster, which were useless for my app.
Now the distribution packages run fine. ---- I found some explanation, seems like a bug from Netbeans 8.1: "asm-all-5.0.1.jar" ismissing in the created "dist/MyApp/platform/core" folder...

My application uses Java 7. I've checked http://wiki.netbeans.org/DevFaqTroubleshootClassNotFound as mentioned in the error message but I found no "verify-class-linkage" issue when I build the app. The only external library I use in the application is XStream which was added using a Module library wrapper. I have really no idea what to try to solve this... Thanks for your help. Jerome Lelasseux
