NSConcreteMapTableValueEnumerator autoreleased with no pool in place - just
When I run my Java app within JBoss I get the following console errors:
* _NSAutoreleaseNoPool(): Object 0x2a826aa00 of class NSConcreteMapTableValueEnumerator autoreleased with no pool in place - just leaking
It does not keep my app from running and everything seems to work. I have searched my code and there are no references to NSConcreteMapTableValueEnumerator or _NSAutoreleaseNoPool. Where is this message coming from? How do I get rid of it?
It's coming from the process (Sender/PID) which you've failed to include in your post.

anyone seen this before? how do i fix it? Thanks : )Are you creating a new thread?
If so, then the first thing you need to do at the start of the thread is allocate an autorelease pool. Check out the threading guide for examples. -
Objc[250]: Object 0x15e509ce0 of class NSRunningApplication autoreleased with no pool in place
Hi there,
After Effects is running extremly slow. I can't really work..
The Console on Mac gives following information:
objc[250]: Object 0x15e509ce0 of class NSRunningApplication autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
Any idea how I could solve this problem? I'm desperate...
Thanks for helping!
I'm using After Effects CS6 on the following Mac Pro:

graphics ATI Radeon HD 5870 1024 MB
software OS X 10.8.5 (12F37)What version of After Effects? Include the minor version number (e.g., After Effects CS5.5 with the 10.5.1 update). Don't just say "After Effects with the latest updates"; give the specific version number.
After Effects CS6 / Version 11.0.2.11
Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
Yes
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
Mac OS X 10.8.5

Do you have any third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU)?
AJA Kona 3G (updated 05/01/2013)
What kind(s) of source footage? When telling about your source footage, tell us about the codecs, not just the container types. For example, "H.264 in a .mov container", not just "QuickTime".
All kinds of, but very often: Quicktime DVC Pro HD 1080i50
If you are getting error message(s), what is the full text of the error message(s)?
following error message in macs console:
objc[615]: Object 0x119a59360 of class NSRunningApplication autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
the numbers (object) are changing
What were you doing when the problem occurred?
I really don’t now. After Effects has always been working very well. I did update the driver for AJA Kona 3G. Maybe that’s the problem..
Has this ever worked before? If this worked before by doesn't work now, what has changed on your computer in the intervening time?
Yes, it worked! Like I said, the AJA update.
Do you have QuickTime installed. (You should.) If so, what version? The answer should be specific, such as "QuickTime 7.6.2".
Yes
QuickTime Version 10.2 (603.17)
What other software are you running?
Adobe’s Production Premium CS6 + InDesign CS6, Maxon Cinema 4D, Microsoft Office
It doesn’t seem to make a difference which app is running at the moment.
Do you have any third-party effects or codecs installed?
AE-Plugins: Trapcode Suite, Twitch, Optical Flares
All worked very well!
Are you using OpenGL features in After Effects?
Yes, with adaptive resolution
Does the problem only happen with your final output, RAM preview, or both?
1. MAIN ISSUE: During compositing After Effects reacts really slow. After a mouse click, it takes a few seconds.
2. I can’t render out anymore. See the attached error messages (german).
Are you using Render Multiple Frames Simultaneously multiprocessing?
No
If the problem is with output, give your exact output settings (both render setting and output module settings). Screenshots help.
Quicktime DVC Pro HD 1080i50 (uncompressed audio)
Other codecs seem to work.
What is the exact sequence of steps that you are taking?
1. No specific. Just trying to work. It’s no specific project, with no specific footage.
2. just render the codec mentioned above. -

On my iphone 4s, when I try to take a pic it flashes the pic for a second, but then the pic doesn't ever show up. It is assigned a number like a pic is there, but it is just a blank white space. When I try to share the pic, it shares the post with blank white in place of the pic.

Threading with connection pool
Hi
My application is an interface to ldap directory. I have not used any ldap open source api to retrieve data from ldap. I have written connection pool that will help the application to connect to the ldap. It's working fine, but it's creating threads which are not invited.
ConnectionPool class takes care of the connection storage and creation, while Housekeeping thread relases these connection when idle after a given time.
Can someone please help in finding the problem in the code that creates additional threads.

Thx for the reply.
// Enable connection pooling
env.put("com.sun.jndi.ldap.connect.pool", "true");
Is this suffice to get the connection pool working,
Should i merely have a thread to maintain the connection with the ldap that uses sun's connection pool; or allow requestes to create new object for the connection and still this pool will hold.
for example in the above code instead to housekeep the thread merely maintain connection with the pool
or
should I directly connect each object with the ldap?
I am unable to understand how exactly sun's connection pool is working and how it should be used. I have gone thru the following example but picture is still hazy and undigestable to me.

Workaround for using Oracle JDBC extension with WLS pooling
Reading the newsgroup I saw that many of us encountered the problems
with ClassCastException when tried to use Oracle JDBC extension
with WLS pooling. I also had.
In this case BEA recommends to use dangerous
method getVendorConnection() which exposes
the physical connection object to your code.
Yes it's really dangerous because of unsafe usage may breaks
WLS pooled connection(s).
Moreover, this practice will make your JDBC code
unportable (your JDBC code in addition to Oracle dependence
became Weblogic dependent):
void doSmth() {
Connection con = ...;
Connection vCon = ((WLConnection)con).getVendorConnection();
// + mess of usage con in one places and vCon in others
// (where Oracle extensions are needed)
// !Don't forget to don't close vCon!
Sux.
I found the workaround.
Introduction
============
Yes the real cause of ClassCastException is that
in depth of Oracle driver the casting
to class oracle.jdbc.driver.OracleConnection
(not to interface oracle.jdbc.OracleConnection)
is performed.
Someone can say that this is bug or pure desing.
Weblogic pooled connection provide dynamic
implementation for all public interfaces
which real physical (wrapped) connection object implements.
Great feature!
But I guess that all interface methods implemented
by simple call-delegation to physical (wrapped) connection object.
In case of oracle.jdbc.OracleConnection interface
this approach doesn't work for at least one its method:
public OracleConnection unwrap()
WLS pooled connection shoudn't implement this method by
delegation to physical connection object BUT should
return physical connection object itself!
// Wrong implementation of unwrap()
// delegation is used
public OracleConnection unwrap() {
return physicalConnection.unwrap();
// Right implementation of unwrap()
// physical connection returned
public OracleConnection unwrap() {
return physicalConnection;
Workaround
==========
1. Develop your own OracleConnection wrapper class:
import oracle.jdbc.OracleConnection;
import weblogic.jdbc.extensions.WLConnection;
public class MyOracleConnectionImpl implements OracleConnection {
private OracleConnection con;
public MyOracleConnectionImpl(OracleConnection connection)
throws SQLException
this.con = connection;
public OracleConnection unwrap() {
return (OracleConnection)
((WLConnection)con).getVendorConnection();
/* Implement all other methods by delegation to con object */
2. Don't get Connections directly from DataSource --
develop your own simple (may be static) utility
class which retrives Connections from dataSource
and returns them wrapped into your MyOracleConnectionImpl
to your code from some method:
puclic abstract class MyConnectionSource {
public static Connection getConnection() {
Connection con = // get it from DataSource
return new MyOracleConnectionImpl((OracleConnection)con);
3. Add attribute RemoveInfectedConnectionsEnabled="false"
to definition of your JDBCConnectionPool within config.xml
You may do it because of you `safely` use vendorConnection --
you don't expose it to application code.
4. Enjoy the Oracle JDBC extensions in your code!
Example:
Connection con = MyConnectionSource.getConnection;
ArrayDescriptor add =
ArrayDescriptor.createDescriptor("your_type", con);
Hope it helps to someone.
Best regards,
Eugene VoytitskyHello Eugene Voytitsky,
Thanks Eugene Voytitsky for your idea
I have tried the solution suggested by You, but it did not work.
It still throws ClassCastException.
I am sorry for posting the whole code of two classes below.
I did this to give you more clarity.
I am also indicating the place where the exception was thrown..

The line 46 in DataSourceConnectionWrapper

datasource cannot be type casted to OracleConnection

SRDemo with application pooling disabled
Hi Steve,
We are building an ADF BC/JSF application that can potentially have a high
number of visitors simultaneously.
So i took your advice on your blog
(http://radio.weblogs.com/0118231/2005/05/09.html) and tested our search
page with application pooling disabled. Unfortunately some functions of the
search page stopped working.
Then I tested the SRDemo application (ADF BC/JSF version) with application
pooling disabled. When application pooling is disabled the SRDemo
application does not work properly either.
So I am wondering...Is there a sample application that works with
application pooling disabled? Among others, I am particularly interested how
the following scenario would work:
1. The user enters a search criteria hits the search button and retrieves a
list of rows in a JSF table.
2. The user clicks one row in the table and he is navigated to a page where
he can view the details of the row he clicked
3. He hits the browsers back button
4. He clicks another row in the table.
5. He is navigated to a page where he can view the details of the last row i
clicked
6. He goes to step 3 and repeats the process as many times as he desires.
This simple scenario works in SRDemo in one context when application pooling
is enabled. It gives a row currency error in another at step 4. When
application pooling is disabled the application doesn't show any errors but
behaves incorrectly.
I would appreciate your insight on how to make this scenario work.
Thank you
YalimI am testing with 10.1.3.0. The change you suggested did not make any difference.The two scenarios I described in my previous post still do not behave correctly.
However I found out that the advanced search tab functions properly even without application pooling once the token validation is disabled. By that I mean that in the advanced search tab I can go through the 6 steps I described in my first post without getting any errors.
I also did some testing in 10.1.3.1. I downloaded SRDemo for ADF BC from the check for updates option in the menu. Then I ran the application with application pooling disabled. The 2 scenarios in my previous post did not behave correctly in 10.1.3.1 either. I must mention though; the behavior of the application was different.
On the other hand the advanced search tab seemed to be functioning properly.
It seems like when application module pooling is disabled, navigating to the details of a record in My Service Requests tab does not function properly whereas the same functionality works just fine in Advanced Search tab under the same condition. -
I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?
Hall Palm Desert,
if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro. -
I have a macbook 4.1 with osx10.6.8 and just added memory (2gig) so I could sync my new IPhone and Ipad. Now I'm told at the apple store that I need to upgrade my operationg system. They said they couldn't help and gave me conflicting advice about what to do. Any ideas? Thanks you!
There are three models of MacBook that comprise the 'macbook 4.1' category, and each of them a little different; however other than 'macbook 4.1' the other thing they have in common is they all are considered Early 2008. Two are white, one black, polycarbonate case, Core2Duo 2.1GHz, 2.4GHz white, 2.4GHz black.
So if you can determine which one, if any of these, is the model build year and spec you have, that would be handy. Did you tell whoever you spoke to the serial number of your computer, so they'd know by looking up the specs to see what the supported maximum RAM upgrade capacity was, and other minimum requirements to make any upgrade to Mac OS X 10.6.8 at all?
If you have the serial number you can do a lookup to 'indentify by serial number' online, and use that information to determine if the computer needs even more RAM to take it past the minimum for Snow Leopard 10.6.8 and then get it ready to upgrade (via paid download from App Store, Snow Leopard gets you that far) and see what the next supported OS X full upgrade would be for the hardware limitations on that old MacBook.
If your MacBook IS a 4.1 build, the highest OS X it could run if it has the 2.4GHz cpu, is Lion 10.7.5. That would be an upgrade from the App store, available to OS X 10.6.8+ computers that access it online. And I kind of doubt how supported a newest iphone etc may be in lion.
everymac.com has a fair amount of information across many years of Apple computing hardware...
Here's the three MacBooks that share the 4.1 designation; first shipped with as much as 1GB RAM upgrade and the other two only a 2GB RAM*, (one white/one black color) according to this information...
• MacBook "Core 2 Duo" 2.1 13" (White-08) 2.1 GHz Core 2 Duo (T8100)
• MacBook "Core 2 Duo" 2.4 13" (White-08) 2.4 GHz Core 2 Duo (T8300)
• MacBook "Core 2 Duo" 2.4 13" (Black-08) 2.4 GHz Core 2 Duo (T8300)
...as seen here: http://www.everymac.com/systems/apple/macbook/index-macbook.html
*But according to MacTracker (free: download database) http://mactracker.ca
these MacBooks can use more RAM in aftermarket specs as much as:
Maximum Memory
6.0 GB (Actual) 4.0 GB (Apple)
Memory Slots
2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM
To get more information use a service such as this...

http://www.powerbookmedic.com/identify-mac-serial.php
The Apple? store or whoever you talked, to may have been as accurate as they could be without further research. Could be you may have a newer or older MacBook, which would change whatever later OS X it could run past 10.6.8. And to go past Snow Leopard, you need to download the last bits for 10.6.x to be able to go and get any later upgrade. The ones that may let a newest iphone or ipad work with it, are past SL10.6.8
Anyway, as you further verify the model build year and configuration specifications, report back.
Good luck & happy computing! -

I can't send emails from Mail. I have three different accounts set up and have the same problem with all. The mail just sits in my outbox. All worked fine until Yosemite upgrade. Recent update has not fixed problem.
I have been experiencing the same problem. My mail app won't even open on my Late 2011 Macbook Pro. It will show as open, but the app will never actually show up.

I recently signed up for a one month trial of adobe pro. I logged in. I cannot convert a single page of PDF file to word or Excel with this trial. I just get the request to sign up for a year. What good is the trial if I can't try it?
Hey vcomfort6,
Please ensure that you are using Adobe Acrobat and not Reader to convert PDF file to word or excel.
Could you tell me whether it is a scanned document? Does this happen with all PDFs or any specific one?
Do you get any error message? What exactly happens when you try doing the same?
Hope to hear from you.
Regards,

Photos in the camera roll of "iPhone cannot be imported because the device is locked with a passcode. Tried just about everything - suggestions?
Because your computer sees your phone, as it would see any digital camera, as long as you have photos in your camera role. Since you state you don't sync with this computer & have a passcode on your phone, that's why you get that message. The only way to prevent that message is either start syncing with this computer; remove the photos from your camera roll prior to connecting; or first turn off your passcode before you connect. Either that, or you live with it.
You shouldn't be storing photos in your camera roll anyway. iPhone camera roll is not designed for photo storage. You should be regularly importing them. -
my iphone came up with that timing circle and just turned off and did not come back on ? even when i charge it now it still wont turn on ,do you know the problem?
If the battery was empty (and it may then take 10 to 15 minutes of charging before it will respond), then have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.
