Script Uninstall of Java

Question

I am trying to uninstall Java via a Powershell script. It works great, but the script removes all java builds. This includes Symantec NetBackup, JReports, and anything that has an embedded version of Java. Is there any way I could change this script to
uninstall just Oracle Java installations?
$java = Get-WmiObject -Class win32_product | where { $_.Name -like "*Java*"}
$msiexec = "C:\Windows\system32\msiexec.exe";
$msiexecargs = '/x "$($app.IdentifyingNumber)" /qn /norestart'
if ($java -ne $null)
    foreach ($app in $java)
        write-host $app.LocalPackage
        write-host $app.IdentifyingNumber
        &C:\Windows\system32\cmd.exe /c "C:\Windows\system32\msiexec.exe /x $($app.IdentifyingNumber) /qn"
        Start-Process -FilePath $msiexec -Arg $msiexecargs -Wait -Passthru
        [Diagnostics.Process]::Start($msiexec, $msiexecargs);
if ($java -ne $null)
    foreach ($app in $java)
        write-host $app.LocalPackage
        write-host $app.IdentifyingNumber
        &C:\Windows\system32\cmd.exe /c "C:\Windows\system32\msiexec.exe /x $($app.IdentifyingNumber) /qn"
        Start-Process -FilePath $msiexec -Arg $msiexecargs -Wait -Passthru
        [Diagnostics.Process]::Start($msiexec, $msiexecargs);
else { exit }

I've actually written a Powershell module that has a number of exclusions already built in to the query and can easily be added to for other products like Netbackup. The module also includes a -Whatif switch that you can use to see the and record the results
without actually uninstalling anything.
I also added a switch to keep a particular version of Java installed if required. The Powershell module and a more detailed description can be found at my blog: http://24by7365.wordpress.com/2014/02/07/uninstall-java-the-easy-way-redux/
Thanks. Will take a look.
