Here's my case:
- I have a JBoss AS 7.1 on which is already deployed an app compiled with Java7 (deployed in the standalone/deployments folder)
- In my workspace, I try to start AS with Java6. This fails (I get an error message dialog).
- I configure the server to use Java7 instead and try to start it again.
I does not complete the startup, it remains stuck at 15%, maybe because the previous startup failed and I can still see an "Update Modules status" job running in background
