How to uninstall (remove) JAVA from OS X Lion

Open terminal (Applications -> Utilities -> Terminal)

To remove JVM enter folowing:

sudo rm -rf /System/Library/Java/JavaVirtualMachines/

Then, clean up the installer records by removing them from /private/var/db/receipts/:

com.apple.pkg.JavaForMacOSX107.bom
com.apple.pkg.JavaForMacOSX107.plist

Now clear any traces of the Java installation from Software Update.

Please copy following file to your Desktop /Library/Receipts/InstallHistory.plist by entering following string in terminal:

sudo cp /Library/Receipts/InstallHistory.plist ~/Desktop

Change permissions on it

chown yourusername:staff ~/Desktop/InstallHistory.plist

Open it in TextEdit and find following: com.apple.pkg.JavaEssentials, remove all dict section which containing this line (it may be several of them)

Example of one of the records:

<dict>
<key>date</key>
2012-04-13T22:13:59Z
<key>displayName</key>
<string>Java for OS X 2012-003</string>
<key>displayVersion</key>
<string></string>
<key>packageIdentifiers</key>
<array>
<string>com.apple.pkg.JavaEssentials</string>
<string>com.apple.pkg.JavaForMacOSX107</string>
<string>com.apple.pkg.JavaSecurity</string>
</array>
<key>processName</key>
<string>Installer</string>
</dict>

When you are finished with cleaning, save this file, exit from texedit. Then change permissions to original by entering

sudo chown root:wheel ~/Desktop/InstallHistory.plist
Copy it to original location
mv ~/Desktop/InstallHistory.plist /Library/Receipts/
