Jars compiled w/ 1.5 should run w/o issue on a 1.6 JVM.  Its if you try 
to go the other way round that you'll have issue.

Thinking more on this, are you doing this up in eclipse?  If so, order 
of items on the CLASSPATH is important (Will be less important after 
HBASE-785 goes in).  Here's my eclipse .classpath:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src/java"/>
    <classpathentry kind="src" path="src/test"/>
    <classpathentry kind="con"
