OS - Solaris Sparc, Solaris i586, Linux
browser - MZ1.4, MZ1.6

Steps to reproduce

1) Installs jdk1.5.0_01

2) Register the Plugin with Mozilla browser

3) Invoke the Mozilla browser and click on Help -> About Plugins

Mimetype 1.5.0_01 is not there. And you still see jpi-version=1.5.0 which should be jpi-version=1.5.0_01

This problem is not there on Windows. jpi-version=1.5.0_01 is there on Mozilla for Windows.
