Java for OS X Lion 2012-001

There seems to be a problem with this update.
I first tried to download it using Software Update on my two Macs running 10.7.3, but it was not avaialble. I was told there were no new upadtes at that time (minutes ago).
I then downloaded the update form Apple's support page and checked the checksum, which was fine. However, when I clicked on the dmg file, a a box opened up saying "There may be a problem with this disk image. Are you sure you want to open it? Opening this disk image may make your computer less secure or cause other problems." There were 2 buttons in that window: Open and Don't Open. Don't Open was the highlighted option.
I decided not to install the update under those conditions. I downloaded the dmg file via Safari, Chrome, and Firefox just in case, but predictabley the problem remained. Is the dmg file corrupt? How come this security update is not avaialbe via software update?
Some other people reported experiencing this on McUpdate as well.
Any explanations, anyone?

Hi All,
This is a follow-up on this issue and a solution after talking to an Apple tech support senior advisor who was not aware of the issue (I am still covered by the Lion warranty). This step-by-step method solves the problem. It is as explicit as possible to help less experienced users as well.
Go to your Utilities folder and open Java Preferences.
It will ask you to install a Java runtime. Do this; it' s OK, and it's needed.
In the Java Preferences window, click "Enable applet plug-in and Web Start applications".
In the Safari preferences under Security, enable Java (by clicking the checkbox).
Go to Terminal and type java -vesion and press return (thanks Barney-15E) and /or
Go to htttp://javatester.org/version.html (Thanks to the Apple Senior Advisor for this tip). Under "Method 1: Ask Java", you should see a blue box that includes a pink one with the updated version of Java. ("Java Version 1.6.0_31 from Apple Inc.")
You can then decide to disable Java in the Safari preferences (under Security) if you so wish.

HT5055 Java for OS X Lion 2012-001 - causing security risks rather than fixing them???

I've downloaded Java for OS X Lion 2012-001 to fix the security issues with Java but when I open it to install it gives me an error message saying don't open it as it has a disk image issue (?) and may make my computer less secure or cause other issues? I don't understand why it would cause security risks when it is supposed to be a patch to fix them?! Is it safe to go ahead and open/install?

Could that be why Apple has released Java for OS X Lion 2012-002 here: http://support.apple.com/kb/DL1515 ?

HT1222 Java For OS X Lion 2012-001

Somebody answered this "You can simply re-download it and delete the corrupted file image", about the Java update for OS X Lion 2012-001 . My question is how do you do that? How do you delete the corrupt image?

Just drag it to the Trash. Then use Software Update for the latest version.

HT5242 Where do I download Java for OS X Lion 2012-003?

I've read this online article about Java for OS X Lion 2012-003, but I do not see where I can download and install it. Any idea where it can be downloaded?

To install software updates on OS X:  > Software Update
If the Apple Java update is not offered, then you don't have Java installed (and Java is not installed by default on 10.7), or you're on a release of OS X prior to 10.6 (no patch available), or you're using a local Software Update Server or local Reposado server and it hasn't cached the Apple upate yet. (And if you don't know what the Software Update Server or Reposado servers provide, then you're probably not one of those.)
Here's the most recent Apple update on this: About the security content of Java for OS X 2012-003 and Java for Mac OS X 10.6 Update 8 (HT5247)
This particular Java 2012-003 download apparently hasn't reached the Apple downloads servers yet, based on some of the chatter, so there's not yet a place to download it other than via Software Update. (And that assumes you need the patch, and many folks - those without Java installed - don't need it.)

HT5228 HT5228: About the security content of Java for OS X Lion 2012-002 and Java for Mac OS X 10.6 Update 7

Is it recommended to install this update? I'm using a Macbook Pro (late 2011), OS X Lion 10.7.3
I ran software update today and this security update didn't even show up in the items to be installed. Someone (i.e. Bob Harris from another thread) mentioned that "Software Update ONLY downloads and installs the patch if you actually have Java installed; it is not installed by default on 10.7" (see thread: https://discussions.apple.com/thread/3853951?tstart=0). Does this mean I don't even have to install this update, since I don't have Java installed? Because I honestly don't know if I have Java installed or not. I'm not exactly a techie.
Thanks.

Does this mean I don't even have to install this update, since I don't have Java installed?
yes
The update provides a fixed Java. If you do not have Java installed and do not want Java installed, then applying the update would result in installing the Java you did not want nor need, hence Software Update did not try to install the Java update.
There are valid reasons for having Java installed on your system, but only if you have a need. For example, there are some 3rd party utilities that are implemented using Java (a programming language). On rare instances, there are some web sites that use Java (very rare these days) to give you an interactive experience, and you happen to want/need to work with that web site.
But for the most part Java is not needed, which is why Apple no longer installs Java by default.
If you have Java installed, then System Preferences -> Software Update -> Check Now, will offer you the Java update. If it isnot installed, Software Update will not offer the update.

HT5242 When is Java for OS X Lion 2012-003 available for download?

Ars Technica published an article to an apple support link about the Java update (http://support.apple.com/kb/HT5242) but, I have yet to find a way to download it (either through Software Update or direct download).

Note that if you need to install Java then you want to download the security update to protect your computer from the extant malware. And, also then see:
Helpful Links Regarding Flashback Trojan
A link to a great User Tip about the trojan: Flashback Trojan User Tip
A related link in the tip to a checker: Malware Checker Dowload Link
Another excellent reference on malware: Mac Malware Guide
A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started.
For now I recommend the User Tip from etressoft to detect and remove or one of the following:
Checking for and removing the "Flashback" trojan
Kaspersky Flashback Trojan Site:Flashback Trojan Detection and Removal
F-Secure Tool: Flashback Removal Tool
Also see Apple's article About Flashback malware.
But if you don't need Java then you should be OK. Just be sure that if you download Adobe's Flashplayer, that you do so only from Adobe's website to be sure you are getting the real thing.

Java for OS X Lion 2012-003 SHA 1 digest does not match posted value

I've downloaded the latest Java update ( http://support.apple.com/kb/DL1515 ) several times and I always get the same sha1 digest which is different from the one posted on the download page.
The one I get is:
SHA1: 4e6fce49e9a3e07533398af8d8b0327136feead5
The one posted is:
SHA1: f3a37aaeace6731c427c76b277c8741d9d6e0220
Anyone having the same problem?
Cheers.

Thanks guys. It was kind of odd as even after reseting Safari I was still getting the old sha1 value but on my iPad I was getting the correct one. The MBP is using Google's public DNS servers and my iPad is using the ones provided by my ISP.
As of a couple of minutes ago I get the correct SHA1 value on my MBP as well so the update probably took a few minutes to get through Google's DNS servers.
And just to prove I wasn't going mad

Java for OS X Lion vs ibank

I have a problem with ibank, I installed Java for OS X Lion, for testing it works, but when I go into ibank, pops up a window that: For a normal future work you have to install a new version of Sun Java Plugin 1.4.0 or older. Install now (version 1.6.10, size 4MB) and continue to work?
But when I install a recomended version of Java for Lion - the same window pops up on and on.
Can you give me a solution, please?

Same as in "java -version" in Terminal
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04-414-11M3626)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01-414, mixed mode)
Since I can't find any trace of logs for the manual install I want to make sure that components that failed to download via Software Update were correctly installed by the dmg.

Every time I try to download Java for Lion (no matter what the source) all I get is a document image labelled "unconfirmed download" and a warning that this type of file may harm my computer. What am I doin wrong?

Even from Apple? > Java for OS X Lion Update 1
Restart your Mac before trying to download the file.
Do you have anti virus software installed or a program like LIttle Snitch?
If you are using Safari to download files, go to the Safari menu bar click Safari > Empty Cache
If that doesn't help, back to the menu bar, click Safari > Reset Safari. Select the top 5 boxes then click Reset.
If you still can't download the Java file, go to ~ / Library / Caches / com.apple.Safari
Move the Cache.db file from the com.apple.Safari folder to the Trash and restart your Mac. Try downloading that file again.
If it still won't download without that dialog, go to ~/Library/Safari. Move the Downloads.plist file from the Safari folder to the Trash.
Try again.
~ (Tilde) character represents the Home folder.
For Lion: To find the Home folder in OS X Lion, open the Finder, hold the Option key, and choose Go > Library

How do I clear Apple's java 6 cache after the 2012-006 update?

Due to some applets that I have to use at work being incompatible with Oracle's Java 7, I have had to re-enable Apple's Java 6 plugin by following the directions here:
http://support.apple.com/kb/HT5559
Java 6 does work for me in all of the browsers on the system. However, I am having some issues with an applet and I suspect that the culprit might be in data left in the cache. Since Java Preferences was removed from Applications -> Utilities, how do I go about removing the cache? I have found /Users/<username>/Library/Caches/Java, but removing this directory didn't solve the issue. Since I don't know if this is really the location that Apple's Java 6 stores its cache, I don't know if removing that directory does anything for clearing the cache.
What is the official way to remove Apple's Java cache now that Apple's Java Preferences is gone? Thanks for any and all help!

Download and install the Java for OS X Lion Update 1 which should reinstall the Java Preferences app.
I have no clue what Apple's position is on clearing caches.

HT1338 Software Update is not finding latest release (April 3) of Java 2012 001 Update for Mac OS X Lion 10.7.3 on iMac mid-2007 that downloaded automatically on iMac mid-2011

Software Update is not finding latest release (April 3) of Java 2012 001 Update on my iMac mid-2007, but it downloaded it automatically on my iMac mid-2011 yesterday. Both are running Mac OS X Lion 10.7.3. When I try to download the update manually from Apple on my older iMac, it downloads okay, but when I try to open the dmg file, I get a warning message saying that opening this update may make your computer LESS secure. Do you want to proceed? (I did not).
Why would Software Update find this update and install it automatically on one iMac and not the other, if they are both running the same version of Mac OS X Lion? I checked the installed software list on my old iMac and the Java update does not appear there. Why would this update make my old iMac less secure?

Recall that Java is not installed as part of Lion.
You have to install it (and are asked if you want to) when you first try to run some java stuff.
Is it possible that the iMac 2007 does not have Java yet?
Try this: open Terminal (from Utilities) and type java -version (exactly like that, with the space before the hyphen).
What do you get?
Consistent with this theory is that the dmg thing gave you the warning - installing java might make your machine less secure because java is a means for bad guys to try to do bad things to your computer.

Java for OS X 2013-001 is not proposed by automatic software update

Hi
As I checked for the new update that apple provides on Feb, 19th : Java for OS X 2013-001
it is not listed by the available updates for my Mac.
Should I install this update after having downloaded it on Apple support web site, or not?
Does this update install the Java soft if we do not have it already
or does it simply disables the famous Java SE 6 applet plug-in?
How can I check if I have the plug-in already or not ?
Thanks for your help.
(I'm having a mid-2012 MB-Pro Retina 15", running mountain Lion)

If you don't have it already installed, it will not update it.

It updates it if you already have Java SE 6 installed. It also temporarily disables the plug-in so that it won't run automatically, but will allow you to re-enable it.

Shut down. Then reboot holding down the command-r keys into the Lion Recovery disk. Select Disk Utility and run Repair Disk.
