I get a NullPointerException in java

I get a NullPointerException in java while trying to compile the exported model. I'm currently using netbeans and I've already added all the jar files on the plugin folder. The stack trace is the following, where myClass is the class of the exported model:

Exception in thread "main" java.lang.NullPointerException
at com.comsol.util.methods.PluginUtil.g(Unknown Source)
at com.comsol.util.methods.PluginUtil.b(Unknown Source)
at com.comsol.util.methods.PluginUtil.a(Unknown Source)
at com.comsol.migration.c.i(Unknown Source)
at com.comsol.migration.c.<init>(Unknown Source)
at com.comsol.migration.c.f(Unknown Source)
at com.comsol.migration.c.a(Unknown Source)
at com.comsol.model.util.ModelUtil.create(Unknown Source)
at myClass.run(myClass.java:18)
at myClass.main(myClass.java:13)

I've double checked everything. I even reinstalled COMSOL just in case the java libraries are compiled on the installation (I don't know it seemed to me something plausible), but I can't get rid of this exception and I can't do anything since the exception is thrown un the run method. Any ideas?
