Err, one is correct and one is not :)
-version does what you expect: gives you information on the JVM that is
executing. Just putting version however is telling the JVM to load a
class named version and execute it, which of course it can't find, hence
the ClassNotFoundException you see.

Curious,
What is the difference between java -version and java version?
In the first case I get:
java -version
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02, mixed mode)
In the second, I get:
java version
Exception in thread "main" java.lang.NoClassDefFoundError: version
Caused by: java.lang.ClassNotFoundException: version
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
Could not find the main class: version. Program will exit.
