ClassNotFoundException for the class javax.rmi.CORBA.Tie

Forge 1 plugin that uses SAP's APIs to deploy ear files to the NetWeaver server fails with ClassNotFoundException for the class javax.rmi.CORBA.Tie. It is used by those APIs for performing remote connections.

The same plugin was rewritten to Forge 2 addon and it got the same exception. Here is the JBoss Modules specific part of the exception trace:

Caused by: java.lang.ClassNotFoundException: javax.rmi.CORBA.Tie from [Module "com.sap.nw.deploy.forge.nwdeploy:1.0.0-SNAPSHOT_d5a54a79-5d83-4f31-bc98-1d6384c4df1c" from AddonModuleLoader]

The SAP code that blows up contains at the row where the exception is the following:

this.out = new MarshalOutputStream(new ByteArrayOutput(this.offset));

The MarshalOutputStream class is from SAP APIs as well and it has in its imports javax.rmi.CORBA.Tie.
