Christian Schneider resolved KARAF-4122.
----------------------------------------
Resolution: Invalid
Assignee: Christian Schneider
I found that transactions work if your <int:enable/> Element is added after the
<tx:enable/> but not if it is added before.
After long debugging I found that your BeanProcessor registers an interceptor
on every bean including the AnnotationProcessor of blueprint.transaction. This
effectively disables the transaction processor.
So the trick is to selectively register your Processor. At a minimum you should
not register with any other Processor.
I created a pull request that should fix your code:

Probably we should document this in Aries Blueprint.

> Key: KARAF-4122
> URL: https://issues.apache.org/jira/browse/KARAF-4122
> Project: Karaf
> Issue Type: Bug
> Affects Versions: 4.0.3
> Environment: Karaf 4.0.2 + 4.0.3, Windows 7 x64, Oracle jdk 1.8
> Reporter: Felix Wassmer
> Assignee: Christian Schneider
>
> When using declarative transactions in Karaf 4 (Aries transaction blueprint
> 2.0.0),
> adding a custom interceptor seems to conflict with the aries TxInterceptor.
> Expected behavior
> Interceptor enabled for service A
> Service A with TxType.REQUIRED calls service B with TxType.MANDATORY and
> service B will be executed in a transaction.
> Actual behavior
> Service B throws exception: No transaction present when calling method that
> mandates a transaction.
> (TxInterceptor was not registered for service A and therefore no tx started)
> Disabling the interceptor (removing declaration in blueprint),
> transactional behaviour works as expected (B is executed in a transaction).
> Custom interceptor + tx behavior works as expected when using transaction
> blueprint 1.1.1 and delcaring transactions in blueprint.
> Example to reproduce the issue:
