Apparently Java has a problem with non-reparenting window managers of
which ratpoison is one:

The symptom is the the java app displays only an empty window and does
nothing else. I found a couple of workarounds and wanted to document
them where they might be googleable.
Firstly, the problem doesn't exist in Java/JRE/JVM 7 so that's one
workaround. The other workaround is to use AWT_TOOLKIT=MToolkit. You
can either set this as an environment variable or prepend it to the
command. I'm using Jmeter so it looked like:
$ AWT_TOOLKIT=MToolkit bin/jmeter
