Description Stefan Negrea 2012-01-04 17:41:02 EST
Description of problem:
CLI methods retrieveBackingContent and updateBackingContent error if the webapp has multiple installed packages attached. A webapp should have only one installed package at any time, so under normal operation circumstances this scenario should not happen. However a database update error could result in having multiple installed packages attached to a webapp. If this happens, the uses will not be able to operate on the webapp from the CLI until the database is manually corrected.

How reproducible:
Every time.

Steps to Reproduce:
1. Have a JBoss AS5, JBoss AS4, or Tomcat server inventoried
2. Manually update the database to have two installed packages attached to a webapp.
3. Use the CLI to find the webapp resource.
4. Call updateBackingContent on the webapp resource.
Actual results:
NPE error

Expected results:
The deployment process succeeds and the database is corrected during discovery.

Additional info:
The scenario described has a high occurrence chance with the old version scheme (eg. version=1.0). The scenario is very unlikely to happen with the new version scheme (eg. version=[sha256=abcd123]) however the risk is still present.
Comment 2 Heiko W. Rupp 2013-09-01 05:59:24 EDT
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
