Java versioning (beta)

Question

When I type java -version this is output I get:

java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b17, mixed mode)

Now I'm wondering, what does -b07 mean? I assume it is a beta version mark (according to other sources: http://en.wikipedia.org/wiki/Software_versioning ), but I cannot find the Sun/Oracle reference that says so.

Does anyone know where to find complete reference of Java version naming?

Thank you in advance.

It's the build number. From Oracle's documentation:

The full internal version number for this update release is 1.6.0_17-b04 (where "b" means "build").

No, it's not a 'beta' mark. It'S the internal build of this version. Nothing for you (or me) to worry about.
