Cool. I think this conversation is probably over.. as to let's wait one
week to see what Howard comes up with..
But let me clarify what I was talking about:
I am talking about concurrent requests (which in my mind translates to #
of request handler threads in tomcat or jetty). And the number of
concurrent users you can actually handle depends on how long your
requests take to process.. Which depends on how complicated or data
intensive your site is, etc etc..
At the bottom of http://code.google.com/appengine/docs/java/runtime.html
"simultaneous dynamic requests 30 *"
"* An application can process around 30 active dynamic requests
simultaneously. This means that an application whose average server-side
request processing time is 75 milliseconds can serve up to (1000
ms/second / 75 ms/request) * 30 = 400 requests/second without incurring
any additional latency. Applications that are heavily CPU-bound may
incur some additional latency in long-running requests in order to make
room for other apps sharing the same servers. Requests for static files
are not affected by this limit."

You're not allowed to have any concurrent threads. What do you mean?
Concurrent requests? There's 30 seconds max response on those. There's
10 cron jobs available... I'm confused. The docs say: "The total number
of requests to the app. The per-minute quotas for application with
billing enabled allow for up to 500 requests per second--more than one
billion requests per month. If your application requires even higher
quotas..." and the free daily quota for requests, divided into
per-minute is: "7,400 requests/minute". So I'm not sure as to what
you're referring.
The quote info is here: http://code.google.com/appengine/docs/quotas.html
Having said all that, you're right - there's no actual requirement that
T5.1 support a beta "early look" software. The only reason I think it's
an issue is that 5.0.x seems to work, so there's some frustration at
play among those who have already upgraded to T5.1 who want to also be
GAE users. Super-awesomely-critical? Probably not. Just frustrating.

Don't forget right now GAE/Java is really really beta. You are only
allowed to have 30 cuncurrent threads? Unless your app is only
serving a small number of users, I can't vote to use GAE/Java for
actual production apps, not yet..
And like someone just said, this just came out a week ago. GAE/Java
is not a priority feature in this landscape, not yet..
Maybe after a month, if Tapestry is still not working in GAE/Java,
then start ratcheting up the pressure and complaints.. sorry.
So I guess if it's really really important for you, you won't be able
to upgrade to 5.1 for a few more weeks.. sorry.

I'm not sure about everyone else, but for me this is a BIG issue and
is one of the reasons holding me back from moving my app to the 5.1
beta. Most likely I'll hold off on upgrading to 5.1 final if it
doesn't support GAE.
Howard was asking earlier about any showstoppers preventing 5.1 from
moving forward - this is one for me. Maybe this would be a good
feature for 5.2, who knows. Is anyone else holding off on taking up
5.1 for this reason ? Other reasons ?

I grepped over the tapestry-core sources for "javax.xml.stream" and
only
found them imported in TemplateParser and StaxTemplateParser.
Would it then be sufficient to just contribute another
TemplateParser which
isn't using Woodstox (maybe the one from 5.0.1.8)?
I just tried to eliminate Woodstox and to use "pure" Stax API for
template parsing. This wasn't that difficult (see
http://derkoe.wordpress.com/2009/04/16/tapestry-51-woodstox/).
With plain Stax I still get the same error in TemplateParser. Maybe
I will try to switch back to the 5.0.18 one when I have time.
Cheers,
Chris
