Description

From https://aptanastudio.tenderapp.com/discussions/problems/3334-cannot-install

An error occurred while processing the invoke block for the command Install Bundle in U:\3.7\configuration\org.eclipse.osgi\bundles\1519\1.cp\bundles\bundle-development.ruble\commands\install_bundle.rb: (TypeError) cannot convert instance of class org.jruby.java.proxies.ConcreteJavaProxy to interface org.eclipse.jface.viewers.IStructuredContentProvider 
org.jruby.exceptions.RaiseException: (TypeError) cannot convert instance of class org.jruby.java.proxies.ConcreteJavaProxy to interface org.eclipse.jface.viewers.IStructuredContentProvider

The code in question is, specifically line 2 here:

ui.rb
dialog = org.eclipse.ui.dialogs.ListDialog.new(shell)
dialog.content_provider = org.eclipse.jface.viewers.ArrayContentProvider.new
dialog.label_provider = org.eclipse.jface.viewers.LabelProvider.new
dialog.input = items

in ListDialog, here's the method being called:

ListDialog.java
public void setContentProvider(IStructuredContentProvider sp) {
  fContentProvider = sp;
}
