Getting UnsupportedClassVersionError at startup

[GoogleCodeExporter]

I'm running a fresh copy of 2.0 on a Linux box. I am just using the config 
files as bundled and I try to start the app using 

sh qfix-messenger-initiator.sh

I get an UnsupportedClassVersionError thrown as below.

Exception in thread "main" java.lang.UnsupportedClassVersionError:

It looks like QuickFIX Messenger is being run from a lower JVM version.

Please note that QuickFIX Messenger 2.0 requires Java 7 (JRE 1.7). Kindly 
update to Java 7 and try again.

• Changed state: WontFix

Yes, that fixed it. Apologies - missed that step in install instructions. 
If this is a common newbie bug, could I politely propose perhaps a new error 
message for JRE version problem?
