Two-column figures and tables disappear when changebar is used

changebar is an old package and it redefines several latex internals in particular the float handling.

It turns out not to be fully compatible with the double float handling in 2015/01/01 latex release (which fixed several bugs in that area)

this works, until changebar is updated:

\RequirePackage[2014/01/01]{latexrelease}
\documentclass[journal]{IEEEtran}
\usepackage{lipsum}
\usepackage{graphicx}

\usepackage[color]{changebar}
\usepackage{soul}
\usepackage{xspace}
\cbcolor{black}
\sethlcolor{yellow}
\newcommand{\edit}[1]{\cbstart\hl{#1}\cbend\xspace}
