I made a quick survey of the source files and found some of the source files have license header issues.

Some haven't a licence header at all, like

hornetq-spring-integration/src/main/java/org/hornetq/integration/spring/SpringBindingRegistry.java

Some have Copyright 2010 while a few others have Copyright 2009

Some have a different license like

(for example hornetq-ra/hornetq-ra-jar/src/main/java/org/hornetq/ra/recovery/RecoveryManager.java)

I'd like to do some clean up to make sure every source files have a proper licence header. But I'm not sure

1) Which is the correct copyright year? 2010, 2009, or 2012?

2) Are all of our source code under same license ?
