Certain characters in binding name cause runtime issues

I have a small test case where I was exploring the use of JiBX, and I decided to try and use the name="whatever" format for the binding tag to name the bindings. I selected two names "old-version" and "543 version" for the restore. Both of these caused a runtime error like so:

org.jibx.runtime.JiBXException: Binding information for class com.cdmtech.jibxtest.Library must be regenerated with current binding compiler
at org.jibx.runtime.BindingDirectory.getFactoryFromName(BindingDirectory.java:134)
at org.jibx.runtime.BindingDirectory.getFactory(BindingDirectory.java:174)
at org.jibx.runtime.BindingDirectory.getFactory(BindingDirectory.java:193)
at com.foobar.jibxtest.Main.main(Main.java:19)

However, "543version" and "oldversion" worked just fine. If these characters are not supported, there should be an error to this effect during the build process. Also, the documentation makes no mention of unsupported characters.

Also, I recieved the following error during the build while trying it with "5.4.3 version" for the name:

Both of these seem like pretty significant errors. I have attached my eclipse project, though you will need to fix the dependencies and build process.
