EtreCheck reports some crashes that have java references.
To my knowledge I do not use any apps that require java.
Java was installed back when I was running Tiger.
Then when I migrated to SL, the java migrated over also.
Some updates were made to java over the years in SL.
I would like to eliminate java from my SL install.
• Is it possible to do?
• Why shouldn't I do it?
• Why should I do it?
• What are the caveats?
Any other input - pro or con would be appreciated.
Thanks,
Jack

After running a few weeks, you should discover anything that actually uses Java. I'd say there are very few apps still using it in most consumer Macs. You're most likely to run across its use at some web site, often a financial one.
Most have found it easier to remove the "JavaAppletPlugin.plugin.", butI don't think that actually remove the Java files/code, it simply prevents a web site from using it.
DO NOT simply remove stuff from the System without considering what it might be used for. <Command line method of removal., Oracle>

I don't have a Java Control Panel in SysPrefs
I am running Snow Leopard v10.6.8
Here's my prefs:

Per your response, I moved JavaAppletPlugin.plugin to my Disabled Plugins folder.
We'll see if that solves the problem.
Thanks,
Jack

Now I am going to move the /library/java to the desktop

So I did what I should have done already.
I booted up in another vanilla account and ran EtreCheck again - problem disappeared - so it's in my primary account.

This weather map, and many others which I like,
need it.
This map is in motion. I just took a screenshot of it.
The velocity of the wind here on Cape Cod was awful yesterday.
I guess its OK to keep it on my Macs?

Things may have also changed in System Prefs. When you have that app open, do you have a "View" menu?
This System Pref pref lets you hide un-needed/seldom used Prefs.
This may be a change after SL.

And way back in an HTML class we used Java to make some very interesting things out of flowers.
I would have to dig into my old class stuff on my site to find them, but they were total fun to do.
Thanks, this is something I dont know much about. So I sure will be watching for your further instructions and info.
Your screen shot was great!

Could be a difference in SL or maybe the results of your house cleaning. 
As long as you don't see any problems in the next few weeks/months, who cares?

... which is the evil one: Java or JavaScript? I know one is more prone to security issues and I can't remember which one I'm not really supposed to be using.

Java is something else that I know very little about, though it did come up in some of our earlier classes, and we made some very odd pictures with it. You can take a flower and make it wobble and look like its reflected in a dish of water and stuff like that. I didn't use it much at all. But it does make these weather pages where you get the whirling motion with wind directions and more.
I dont understand much about Flash either, nor did we get it in class.
Somebody here will explain it much better than I ever can.

javascript is, by definition, a "scripting" language (like AppleScript, PHP, Python, etc.). It is used (and abused) on the web to do things that plain html cannot. It is also a major vector for malware and accessing things on your computer, behind your back, of course. It must have a browser to allow it to run. Thankfully, CSS3+ and HTML5 are making it less needed. It's the main reason I keep ad blockers running.
The two things are completely different 'animals'. I usually use a lowercase "j" for javascript to imply my disdain for it as opposed to a capital "J" since it is a commercial product.
Handy things javascript can do: Transmitting information about the user's reading habits and browsing activities to various websites. Web pages frequently do this for Web analytics, ad tracking, personalization or other purposes. See the "Security" section on <this Wikipedia page>.

The last classes we took brought us right into HTML5 and CSS3. But still we used JS, though it so difficult for me to write stuff with it.
The last class in JS that I took was more for making business pages, which I am not interested in at all. With pop ups and more.
So I got to really like HTML5 and CSS3.
Oh, yes indeed, AdBlock is the way to go! I will study your links further.
The only reason I used JS is to make slide shows and do some pretty and silly things on my sites like changing colors of our cat's eyes, triple mouseover stuff, and much more.
You inspired me, and for the last hour Ive been looking thru my old pages, and some are just hilarious, and tons of fun.
But I dont think I can put my links up here? Nope, I just googled me on TS, and stuff is all there.
I do have some fun pages, mostly photos and slide shows.
Off to get ready for Thanksgiving,,,,,,,,

This makes a time stamp on your page.
