You'll need t ask Jeremy on bootstrapping but you don't need to
bootstrap the container to test you component extensions - the Spring
and Groovy examples show how to do this.
The Groovy issue was brought up on this list earlier and it's not
related to Tuscany at all. It's a problem with the version of ASM it
is using. I don't have the Tuscany thread right now but if you do a
search, it involves deleting a version of ASM from you maven repo. If
you can't find it, let me know and I'll look.

In terms of how to specifically improve the extensibility story,
my opinions have been embodied in the sandbox code and
presentation Jeremy and I gave the other week (there are several
slides providing high-level overviews of how to extend things) :-)
Comments on that approach would be appreciated.

In order to better understand our extensibility story and how we
can improve it for M2, I'd like to experiment a little with our
extensibility APIs and try to develop two simple extensions:
- a jruby implementation extension (I won't be starting from
scratch, we already have an initial implementation, but I'll try
to add support for properties, references, lifecycle management,
and deployment maybe)
- a simple TCP/IP (socket) binding implementation
I'll bring any questions and issues I run into and improvement
proposals on the mailing list and I'm thinking about keeping
track of this on a Wiki page as well.
I'm going to start with the component implementation extension.
If anybody wants to help and start the TCP/IP binding extension,
please let me know and we can coordinate (I think we'll find
common techniques and patterns between the two).

I'm starting with both. Interestingly most of the differences
between the two sets of SPIs are not related to the spec changes to
support recursive composition, I found this surprising.
I'm also going to propose, in the form of prototypes, improvements
to the SPIs, there are good (and less good) things in both code
streams, and I'd like to try to combine the best of both.
Right now I'm prototyping this with the head stream, as I don't
see yet how to run a simple sample with the code in sandbox, I'm
running into the following issues:
- I cannot find TuscanyRuntime anymore, has this been removed? has
the mechanism for a client to bootstrap the runtime changed? is
there a sample anywhere?
- I was counting on the groovy container that you pointed me to
yesterday to understand better the new SPIs but I'm not able to
build it, the test cases fail with:
