Java SE 6 Update 10 RC leak memory

I install Java SE 6 Update 10 RC from JDK6 Update 10 RC and open
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
When I push "launch" button , I saw only first JavaApp, next I don`t see nothing.
Processes have 5-6 "javaw.exe" on task manager (Windows2003s) ~26MB
Then I remove SE 6 Update 10 , reinstall Java SE 6 Update 7 and now all are wonderfull!
All Apps execute without problem.
Sorry for my English.

[Java 6 Update 10|http://java.sun.com/developer/technicalArticles/javase/java6u10/] provides some nice enhancements for deploying Java to the Desktop, a nice new look and feel and some other nice additions.
Also, JDK 6 Update 7 is the latest, officially released version at the moment. The Update 10 is only a release candidate (that means it is what might become the final Update 10, but can still change).
For normal development (and especially when you're just starting to learn) there shouldn't be too much difference, so choose whichever you want.

Since the itunes 10.4.1 update I have memory leaks problems.

Since the itunes 10.4.1 update I have memory leaks problems, Itunes used memory start at about 100 megs as usual but when it play the ram usage climb about 4 kb per second ( one time I had itunes using 690 megs !). I had to periodically close and restart Itunes to clear the memory.
Someone has suggestion to resolve this problem?

Same issue, Running Windows 7 x64 with 6 Gigs of RAM and have iTunes 10.4.1 32bit version.

Why does Firefox 4 (4.0.1 specifically) leak memory?

'''Answer:''' I figured it out.
History lesson first. Ever since the 4.0.1 update, Firefox 4 has been crashing A LOT. It's gotten so bad that FF4.0.1 will eat memory with no end in sight and eventually Windows (Win 7 64-bit) forcefully close the program due to an out of memory error.
I have 8 GB of RAM installed. And, it would crash once it exceeds 1.5 GB of RAM used by Firefox 4. I've seen Firefox 4 go up to 1.85 GB of RAM in Task Manager. This is with 20 tabs open.
With the add-on Leak-Monitor, I've narrowed down the issue. Having only Leak-Monitor as the extension installed, all pop-ups point to how '''poorly Firefox 4 handles Javascript'''!
MSNBC Leak Monitor issue:
[http://www.octoberasian.com/tech/text/FF4-Leak-Monitor_MSNBC.txt Leak Monitor log from MSNBC.com]
I've gotten more pop-ups from even support.mozilla.com because of the Javascript on this website.
Firefox 4.0.1 is leaking memory from every Javascript on every website I load. It's leaking memory as we speak with only this page loaded (one tab).
FIX IT! Firefox 4 is poorly handling Javascript, especially when multiple tabs are opened.

octoberasian: I, too, am experiencing this phenomenon. I shut my system down, pulled the EIC cable, held down the power button - then replugged and rebooted. I closed down every unneeded application that I have set to auto-start. Finally, I opened a single Firefox 4.0.1 window and let it sit. It began with consuming 43 Mb of memory. By afternoon - about 5 hours later - it was up to 203 Mb. There is definitely something very wrong with this version. It does the same on all the machines we have, sans our server. We don't use the server for anything but being a server & it has some version of Firefox 3 on it anyway. No Java Scripts were running, nor were any Adobe ARM or any plugins. I noticed when plugins run - the memory leakage goes into overdrive. Hey, I'm just sayin'...

Java 6 you can't as Apple maintains it, and Java 7 you could if you uninstall it and Oracle provides the earlier version which they likely won't his last update fixed 37 remote exploits.
Java broken some software here and there, all you'll have to do is wait for a update from the other parties.

Imapd service "Leak Memory"

I already have Java Communications Suite 6 Working , but, I have a Leak Memory problems with imapd process.
I have the server with 30 imapd process, 30 mshttpd process, and 30 pop process running to balance the load of the users.
All work fine(the CPU is 100% idle, the RAM is 80% available=6GB) when I access via browser(Chrome,Firefox), too when I access it with the traditional clients IMAP (Outlook, ThunderBird,etc).
The problem is that if one user want to copy(not just view) locally all your emails to your laptops/pc, the imapd process eat more than 3GB(instead of 80MB) of RAM and the system is getting slower.
If the user cancel this process(copy via IMAP all your emails) the process dont freedom doesn't release the memory and the system getting slower.
Actually my solution is:
# kill -9 <PID_imapd>
Some times when I kill the process the problem going to other imapd process, so in this case the solution is:
/opt/sun/comms/messaging/sbin/stop-msg
/opt/sun/comms/messaging/sbin/start-msg
I think that this problem is a bug but I dont know what is the patch.
May you help me? Any idea?
My system is:
A X2100 with one socket AMD Opteron 2600Mhz, 8GB RAM, 2 x disks 750GB in mirror with Solaris Volume Manager, Soalris 10 HW 10/08.
Thanks.

The rest of the imapd process(29) in this moment just load 40-50MB(when those are free).
If we kill the process 16673 the user connect to the next imapd process and the problem persist whit the same patology: eat memory and CPU, and slow the system.
So, we think that is not normal and maybe we need patch the system to solve the problem.
We will to test the 64Bit version in this moment and we will post the results.
Thank

Leak memory in xerces DomParser

Hey,
I have " leak memory " in my Java application (Stand alone).
I suspect that this leak caused by xerces DomParser.
i reached to this conculsion after using in Jprobe as a memory debuger.
Does any one has a similar problem?
Thank you.
code:
DOMParser parser = new DOMParser();
parser.parse(new InputSource(new FileInputStream(schemaFile)));

Hey, which Version of Xerces do you use?

Simple JSP leaks memory?

Simple HelloWorld.jsp leaks memory significantly. Tested with SoapUI setup with 40 clients driving load. At around invocation 100,000 the WLS server simply leaks enough memory to hit the upper heap size and dies. I'm running V10.3.2 (latest) in Production mode with the JRocket JVM. I also tried the same test with HelloWorld.HTML file and found no memory leaks, it runs HTML test fine up to 1,000,000 invocations with no memory or thread leaks.
This test can not be any simpler.
Also, performance goes down significantly as memory leaks! I go from 500tps down to 100tps just prior to running out of memory.
The JSP file is extremely simple, here's the code:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Hello World JSP</title>
</head>
<body>
<p>Hello World!</p>
</body>
</html>
Why would such a simple JSP file cause the WebContainer to leak memory? I'm at a loss here.
Edited by: user9200447 on Feb 26, 2010 10:47 AM

It depends on the test being run. One possibility is it may be due to implicit session objects.
Try using session=false otherwise session objects are created implicitly for this jsp. Dependng on sesson timeout, hits and java heap memory size you can run out of memory

How to avoid the case of leaks memory in Object Oriented Programming

Hi, Everyone, I am writing a simple web-baed application for JSP and Servlet, I pass all data from JSP to Servlet, It is due to the number of row of record are variable, so I should write a Java Instance class to stored to specific data in a Java Object, and then stored those object in a arraylist In the Servlet class, and then pass the arraylist in to a session, to pass the session from the servlet to another JSP......
But some thing I am worried about is that if the no of row of record user input is large, then the number of object stored in the arraylist will also large. I am worried it will serious leaks memoary in my server. Because my server always occurs "Out Of Memoary Exception" in Tomcat, So If I use the above method. I affarid the memory will be further leaking in my server. So What can I do? Is it having any better method to prevent memory leaking when using Object Oriented Programming(Except using Hibernate)?
Can Anyone be help me?
Thank you very much for All, THX

Because many people say that the large amount of
using Object will lead to "memory leak", I am worried
about the size of object I use is too large and then
it will construct "memory leak". No it will not! You get a 'memory leak' by holding references to objects you no longer require.
>
The detail of my case is that:
In my web application, there is a session variable
pass through from one servlet to another jsp/servlet.You should only place small amounts of data in the session. If you need forward from a Servlet to a JSP (or JSP to Servlet) then you should place the data object in the request (using the setAttribute() method), not in the session. In this way, when the session is re-claimed so will be the data object.
And this session variable is stored a Instance Object
(which is a class write by me) with the following
issue:
1) This instance object having "has-a relationship"
with another four instance object (all are the
classes write by me)
2) This instance object having "has relationship"
with a arraylist, this arraylist is stored about 4-5
instance object(all are the classes write by me) .
If this object having the above issue, Will this
object construct a "leaks memory" when this object
stored in the session and pass through servlet to
another jsp/servlet?

Hi Ginny,
There are no more updates for Java from Apple for 10.5.8, the only way to get a Java upgrade is updating your OSX.
Snow Leopard/10.6.x Requirements...
General requirements
   * Mac computer with an Intel processor
    * 1GB of memory (I say 4GB at least, more if you can afford it)
    * 5GB of available disk space (I say 30GB at least)
    * DVD drive for installation
    * Some features require a compatible Internet service provider; fees may apply.
    * Some features require Apple’s MobileMe service; fees and terms apply.
Which apps work with Mac OS X 10.6?...
http://snowleopard.wikidot.com/
It looks like they do still have it:

And it's been reported that if you have a MobileMe account Apple will send one free.

SystemUIServer leaks memory, possibly related to spotlight

SystemUIServer leaks memory. Immediately after reboot it occupies about 8 to 9 MB (real) on my system. Climbing to more than 17MB after only 30 minutes. After 3 days, 20 hours of uptime total real memory consumption of the SystemUIServer process was 441MB. Upon researching the process I found this forum devoted to Spotlight and interaction with SystemUIServer. Testing, I found Spotlight was unresponsive, the tool would not pull down and it didn't respond to the keboard shortcut.
Killing SystemUIServer brings the process memory usage back down but it continues to climb as it runs. Spotlight became responsive.
System is fully patched and updated.
I also noticed after rebooting from update that iSync logs messages like the following in console.log:
2007-08-09 05:54:54.180 SyncServer[3857] A Sync Server is already running on this computer, exiting process.

I guess my question would be, does anyone know when Apple is going to fix either Spotlight or SystemUIServer so it doesn't leak/crash as seems to so common here in the discussion groups?
Probably need a bit more troubleshooting...
My uptime is now 3days 20 hours -odd coincidence.
SystemUIServer is using 10.96MB Real Mem.
So, I don't know if I would expect Apple to already believe that there is a problem needing to be fixed. Really, don't think anything in this forum can be considered "common." For a core function of the OS, the Spotlight forum is now one of the quietest of all the Tiger forums- only one that sees less action is UniversalAccess.
Anyway, I'm not sure why you're having a problem with memory leaks in SystemUIServer or with Spotlight, and I'm not enough of a developer to tell you how you could debug it. All I can say is that your situation is not the norm and that there is likely something specific to your situation that is causing it. The unresponsiveness of Spotlight may very well be a side effect of the memory leak which is being caused by something else on the menubar.

Windows 7 x64 RC, Java 1.6 update 14 Eclipse crash

Hey folks. I've poked around on the forum and Google, but I can't find anything recent matching my problem. I'm posting this on this forum, as well as the Eclipse forum, in hopes of resolving this quickly.

As of today the following is the list of windows OSes that the lastest version of Java (Version 6 Update 16) supports.
Windows 2000 , Windows XP , Vista , Windows 2003 , Windows 2008 Server
Note carefully in the above that it doesn't say windows 7.
Thus if you attempt use it on Windows 7 it might or might not work. It might not work initially and it might not work in some odd way that you are only going to discover on Sunday night at 2am when your 24x7 app is no longer 24x7.
Now if you want Sun to fix this problem (no version for windows 7) then the very best way is for you to establish a sales or support relationship with Sun. And then use that to push for a version. Since 1.7 is supposed to be released shortly you are going to need a really big monetary relationship to make them do anything. (I looked and I couldn't find anything that suggests 1.7 will support Windows 7.)
Other than that your choices are limited to the following.
- Tinker with your OS and java in the hopes that you might get it to work and that it doesn't fail in some mysterious and serious way later on.
- Don't use Windows 7.
- Don't use java - at least not from Sun. And I just looked at JRocket and it doesn't support Windows 7 either.

I have a brand new iMac, Yosemite 10.10.1, Java Version 8, Update 25, however, I still get a window when I open Adobe Photoshop CS5, that indicates that I need to install Java SE 6 Runtime. Any suggestions?

Java should be downloaded directly from Apple:

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 5.0 Update 6- Problem Installing ?

Hi, My name is Mark, Iam a new member to "FORUM" Iam having technical difficulties trying to download, and install Java 5.0 update 6...my computor is using IE-6 browser. early today the Java 5.0 downloaded... and was trying to add the files needed for the program, when I received the following error message: " We encountered an issue while trying to automatically install Java software onto your machine". If you encounter an error. check the top of the browser (see image above) for a yellow bar that reads " This site might require the following Active X control: J2SE Runtime Environment 6 Update 1 from 'Sun Microsystems,Inc. .Click the yellow bar and choose "install Active X Control..." to allow installation to proceed. However "the Yellow bar image never appeared on the browser page; ? I have been told that my XP windows Firewall or spyware protection software, I have on my computer, is 'causing the issue. However I turned off the firewall and shut the spyware program off... I again tried to install Java 5.0 (Update-6) however when the files try to load-up... it stalls,so therefore (installation Fails etc.) I tried to troubleshoot the issue with the alternative method: downloading MS-Java X 86 from a another internet site, and tried to install and run it...received this error message: "Installation Failed" -not a valid win 32 application" ...I hope someone here in this forum has the correct information -or- how to fix or resolve this issue ? Thank's

Hi again, I donot actually download the intallation package, the entire program setup is at the Java download site: and is installed on ones computer right at the website: a window appears that says "Java (TM) SE Runtime Enviorment 6 update 1 license and prompts me to either go with a typical setup or choose the custom setup. once I click Typical setup the process begins to install it loads some files and freezes up or stalls when it gets half way point(status)" Copy New Files" or near the end of it .

Pogo player fearful of Java Secy. Update

I have iMac 10.7.5 Lion, 2.5GHz,intelcorei5 4GBRAM. I play POGO games online all the time, which is JAVA. I've read the recent Java Security Update which seems to this will uninstall JAVA from my iMac and in order to play POGO games or use any JAVA related stuff I would have to download from Oracle.
Before touching this, I've waited to see what issues might come along that will make me crazy if I do this security update.
There seems to be great confusion. Since I am a paid member of POGO, if I cannot play their games because I uninstalled JAVA and then the Oracle download creates problems in opening games , crashing, or whatever, I wonder if I should wait until someone actually knows what they are doing? Apple people have enough difficulty trying to play online games as it is. I'd like someone who is a player and has been through this with POGO after doing the Java Secy. Update to give the the real score. Thanks.

I just got off phone with AppleCare about same issue. Here is how to fix:
