Ok well, once I turned on logging I was able to figure out the root cause, but I don't know exactly why yet. I'm assuming that the stack trace is fairly obvious. The question is. "What is the correct way to resolve it?"
Side note: I really need to add a logging toggle in Forge itself, but it would
need to go into the launcher, just haven't gotten around to it yet. Currently, one needs to edit the build to enable logging *gulp* (Search for "LOGGING") in the source and you'll see what I mean :/ That might be my tomorrow (in addition to working on this.) I'm going to be cutting a Beta5 very soon because of some issues in the recent Beta4.

Here's the steps to reproduce (there's quite a few, sorry for that, we
should have this down to two in the next release) :
Download
http://downloads.jboss.org/switchyard/releases/v0.3/switchyard-installer-0.3.0.Final.zip
unzip switchyard-installer-0.3.0.Final.zip
cd switchyard-installer-0.3
unzip a jboss-as-7.0.2 somewhere to install into, give that location to
the installer
Answer (y) that you would like to install the SwitchYard Forge plugin
If you have FORGE_HOME set to forge-1.0.0.Beta4 or SNAPSHOT, it may
error out on trying to write to the ~/.forge/plugins/installed.xml
because JARs have moved around - in this case add the following line to
installed.xml :
<installed>
<plugin name="org.switchyard.switchyard-forge-plugin" slot="0.3.0.Final"/>
</installed>
Change FORGE_HOME to forge-1.0.0.Beta4 or SNAPSHOT
Edit
~/.forge/plugins/org/switchyard/switchyard-forge-plugin/0.3.0.Final/module.xml
Change <module name="javax.enterprise.cdi-api"/>
to <module name="javax.enterprise.api"/>
Change <module name="org.jboss.forge.shell-api"/>
to <module name="org.jboss.forge.shell.api"/>
