The Java VisualVM (jvisualvm.exe) doesn't specify its publisher, product information.
For all *.exe under \jdk1.6.0_12\bin, only <jvisualvm.exe> doesn't have this information.

Tested OS: Windows XP, Vista
       jdk: 6u12-b04

Steps to reproduce:
- Install jdk 6u12 onto the test system.
- Go to <System Driver>:\Program Files\Java\jdk1.6.0-12\bin
and check the properties of jvisualvm.exe
If you don't see the "Version" tab listed, then the issue is reproducible.

- One other way to confirm the issue is to use the sigcheck tool from MS. This way, you will see all n/a listed for its publisher, description, product, version.....

Here's the output of sigcheck run against 6u12 jvisualvm.exe:

C:\sigcheck>sigcheck "C:\Program Files\Java\jdk1.6.0_12\bin\jvisualvm.exe"

sigcheck v1.54 - sigcheck
