It seems that you did not set the
AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL
to the endComp. You could try something like:
endComp=new Compsite() ;
endComp.addComponent(timeUUID) ;
endComp.addComponent("ACTIVE", StringSerializer.get(), "UTF8Type",
AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL) ;
Hope this would help.
