JIRA fails to start using AMPS 4.1.4 atlas-run with JDK7

If JIRA is not compatible with JDK7, it would be nice for AMPS to error out early and inform the user that JDK7 isn't supported. I was wondering if this was something I'd done wrong...

My environment:

• AMPS 4.1.4
• Oracle JDK 1.7.0_07
• Reproduced on OS X and Linux

Steps to reproduce:

1. atlas-create-jira-plugin
   • Selected JIRA 5.0 plugin
2. atlas-run from within the new plugin directory

Results:

• atlas-run reports "JIRA startup failed, JIRA has been locked."
• See attached log file for errors, the first one being:

Workaround:

• Switch to JDK6
