Improved error message when maven 2.1 is run with jdk 14
--------------------------------------------------------
Key: MNG-3561
URL: http://jira.codehaus.org/browse/MNG-3561
Project: Maven 2
Issue Type: Improvement
Components: Command Line
Affects Versions: 2.1-alpha-1
Environment: Maven 2.1-alpha-1-SNAPSHOT
Reporter: Paul Gier
Priority: Minor
Currently if I try to run maven 2.1-alpha-1-SNAPSHOT with java 1.4 I get the
standard jvm errors about wrong class type. It would be nice to have some
better error message saying that java 1.5 or higher is required. This could
probably go into the startup script.
