I think it would be nice if we would also print the HOTSPOT_VM_DISTRO equivalent (it seems to be PRODUCT_NAME and PRODUCT_SUFFIX) for JDK:

# JRE version: 7.0_04-b20
# Java VM: OpenJDK 64-Bit Server VM (23.0-b21-internal mixed mode solaris-amd64 compressed oops)

More like this:

# JRE version: Java(TM) SE Runtime Environment 7.0_04-b20
# Java VM: OpenJDK 64-Bit Server VM (23.0-b21-internal mixed mode solaris-amd64 compressed oops)

or in the OpenJDK case:

# JRE version: OpenJDK Runtime Environment 7.0_04-b20
# Java VM: OpenJDK 64-Bit Server VM (23.0-b21-internal mixed mode solaris-amd64 compressed oops)

This would give us an idea what JDK was used.

I agree (and removed hotspot-comp).
