If this is only for local transactions, then why not add the API but not extend the WSDL?
{quote}
I agree, that sounds like a good approach. Also, I don't think we should add the
proprietary method to BAParticipantManager interface. Instead we could add it to the impl
of the interface. It's there if you look close enough, but it's obvious you are
going "off piste". Of course, we should add a javadoc to the new method that
explains why it is there and how it is not standards compliant.

I'm not sure what you mean by "not appear in the public API".
{quote}
I meant that we shouldn't put the method on any of the supported XTS interfaces that
we offer (like BAParticipantManager for example).

if this is added to make a quickstart work then someone will find it and use it anyway
{quote}
The quickstart uses a (proprietary) annotation which causes an interceptor to be fired.
The implementation of the interceptor would use this proprietary method. So yes, it is
there if they look at the Narayana source, but not if they look at just the quickstart
source. I don't think we can protect from this as Narayana (and any middleware for
that matter) is going to be full of code that could in practice be callable by the
developer, which could at the least break portability and at the worst destroy the
integrity of the application and its data.
Resolve the ParticipantCompletion race condition

Key: JBTM-1718
URL:
https://issues.jboss.org/browse/JBTM-1718
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: TXFramework
Reporter: Paul Robinson
Assignee: Gytis Trikleris
Fix For: 5.0.0.M4
This issue is documented here: JBTM-1429
In the documentation for JBTM-1429, we state that this issue is unlikely to happen in a
distributed environment. This is true, however, the Compensations API is designed to work
local-only as well as distributed over WS-BA. Therefore it is much more likely to happen
in a production environment.
Therefore we need to remove this race condition. It can be done in a proprietary mannor
as we are not interoperating with another implementation ion local-only mode. When
distributing the transaction we fall back to the standard protocol that is susceptible to
the race condition. However, as we stated in the docs, this condition is unlikely to
manifest in a distributed environment.
