Undeployment of an .ear through HDScanner leads to a deploy() call on the deleted deployment
--------------------------------------------------------------------------------------------
Key: JBAS-7790
URL: https://jira.jboss.org/jira/browse/JBAS-7790
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: ProfileService
Environment: JBoss AS trunk r102035
Reporter: jaikiran pai
Assignee: Scott M Stark
On the current AS trun (r102035):
- Start the "default" profile of the server with a .ear file in the deploy folder
- Once the server has completely started, delete the .ear from the deploy folder
- HDScanner is triggered and it undeploys the deleted .ear *but also* triggers a deploy on this deleted .ear which results in:

Notice that the NPE is triggered through the deploy() flow. A quick look at the code indicates that this is because the org.jboss.system.server.profileservice.repository.HotDeploymentRepository on a call to getModifiedDeployments() returns that .ear as both REMOVED as well as MODIFIED. It returns it as modified because the call to getModifiedDeployments() internally leads to checkForAdditions() method which uses a *cached* VirtualFile for the "deploy" folder. This cached VirtualFile returns the .ear as one of the deployments, even after the deployment has been removed.
