Martin Malina commented on JBIDE-16950:
---------------------------------------

I now understand why I couldn't reproduce it last time I tried (today I can). 
I used these steps:
1. Start AS 7
2. Create dynamic project
3. Deploy the project

In this scenario, the duplicate scanner is not added at server start.
When I tried again, but this time the project was already created before server start (so effectively 1. and 2. were switched),
I could then reproduce the issue - after server start, the duplicate deployment scanner was added.
{code}
11:57:20,349 INFO  [org.jboss.as.server.deployment.scanner] (MSC service thread 1-2) JBAS015012: Started FileSystemDeploymentService for directory C:\JBDS\jboss-as-7.1.1.Final\jboss-as-7.1.1.Final\standalone\deployments
{code}
This is probably because the bug had something to do with the mechanism that ensures each module has a deployment scanner that will notice it once deployed - so no module in workspace means no problem.

(Note that all this time I've been using Beta1 B79 which does not contain respin-a fixes such as JBIDE-16866. But then I tried the latest build B82 and the result was exactly the same as described above. So no difference was observed between the two builds.)

> I'm experiencing this issue where, after doing a full publishing, the deployed webapp is being undeployed right after being deployed.
> See http://screencast.com/t/JmwA0TlBrDWX
> The most reliable way (even though it's not 10% of the time) to reproduce the issue is to deploy a webapp to AS 7.1.1 or WF8, then remove it from the server, deploy it back. That's when the problem occurs :

> Also, pretty quite frequently, deployment just fails (but I haven't been able to figure out a decisive pattern yet) as the server thinks deployments are duplicates (see screencast)
