issuing 'jruby -v' causes Java exception "Ruby: org.objectweb.asm.ClassReader java.lang.ClassNotFoundException: org.objectweb.asm.ClassReader"

When asking the 'jruby' binary to provide version information using '-v' switch, it completes, but spews a Java Class exception error. This did not occur with 1.7.0-pre1. Testing on latest available Oracle JDK 1.7.0_05.

output shown:

[ctusa@archbox ~]$ clear;java -version && jruby -v
