ping for manual update is "jau" instead of "jau-m"

How to reproduce??

1.) Install any of the previous version say jre 6u14

2.) Set the Update servlet path to update to 6u15 (latest plus build)

3.) Launch the JCP and do the Manual update

4.) Install the 6u15 update

Expected behavior:
After 6u15 plus build is installed in jusched.log file the ping for manual update should be "jau-m"

Actual behavior:
Ping for manual update in jusched.log file is "jau"
