After some additional testing, I have found the following:

1. Install Rails 1.1.1 (via upgrade from 1.0)
2. Create test app and run the console  
==\> All works as normal
3. do “script/plugin install engines” (installs engines v 1.1.1)
4. Run the script/console again

In the console, you get

railp 579 $script/console  
Loading development environment.  
/usr/local/lib/ruby/1.8/test/unit/assertions.rb:265: warning: already  
initialized constant UncaughtThrow

I’m not certain if there are any other side effects of this.

I’ve noticed this happening too - it has something to do with  
reopening the Test::Unit::TestCase class in ‘testing\_extensions.rb’.  
I’m looking into it, but let me know if you find something. Might be  
an idea to raise a ticket too…
