JBoss BPM Suite CLI installer: broken on first step

When I run...

$ java -jar jboss-bpmsuite-6.3.0.GA-installer.jar -console

...to install JBoss BPM Suite via the command line, the first step is to agree to the licensing agreement:

press 1 to continue, 2 to quit, 3 to redisplay.

Unfortunately, pressing (entering) "1" has the same effect as entering "3" (redisplay), so I can't get anywhere. (Entering "2" quits the installer just fine.) See screenshot for a visual of the context.

Needless to say, I'm off to a pretty bad start. Anybody have a fix?!?

Thanks!
