Jmc.dll crashes java.exe

First of thanks Sun's engineers for hard work on Java and JavaFX! I really enjoyed the features and demos from javafx.com.
Unfortunatly all of the demos involving media playback are crashing java.exe with jmc.dll being guilty (probably access violation - jmc.dll in the error dialog reports 0.0.0.0 version - but not sure). Well, I think it is my system's fault, because when I got rid of all codecs that could play mp3, java.exe stopped crashing (at least for DraggableMP3Player demo, SimpleVideoPlayer crashes without writing hs_err), but gave me MediaUnsupportedException. Regarding fixing my system - I'd like to avoid the pleasure of reinstalling Windows and I think it would be good for others having this problem to nail the cause of it. Could you explain how jmc.dll is dealing with platform codecs? How it checks what is installed? Does anyone else seen jmc.dll crashing java? Could it be hardware issue (I have nforce2 sound card)?
I've created issue [http://javafx-jira.kenai.com/browse/RT-2530] if you have the same problem please vote for it (you first need to register for free :))

I sure have put some work in this bug. I hope this will be gone soon :). I'm somewhat surprised that nobody seen it beside me - no votes, no blogs about it. But UnsupportedMediaException is known for sure and I believe it is related (that's why I've voted for it). Thanks for all your sweat, tears and blood you put in JavaFX! :)

My Applet crashes java.exe to crash

Ok, I'm not sure why, but on some computers my applet is making java.exe crash. When i attach a debugger to java.exe when it crashes I see a "Access Violation Error". The oddest part is that while one computer will crash and another identical computer with the exact same setup wont. The crash happens the moment the applet starts.
Now I've done just about everything i could to figure this out. I've installed uninstalled and reinstalled java. I've run ram, hard drive, cpu, ect tests all reporting no problem. I've disabled anti-virus and did the uninstall and reinstall again. I've installed older versions of the java. I've resigned my jar file, created a new key and then resigned. Practically the only thing i have not done and is not a viable solution is reformat/replace the computers. So I'm left thinking it might be something in the applet that is causing it.
It could be in the applet parameters but i doubt it.
Pram fp is about 5,000 characters long
Pram VerfyType is about 1 character long
Pram Arg1 is a max of 11 characters long
Pram Arg2 is a max of 11 characters long
This applet is meant to interact with a program on the computer that connects to a variety of fingerprint scanners that we use and passes information form the internal site to the scanner and vice versa. So it just starts a loop back socket. For the loop back socket, i have tired 127.0.0.1 and localhost which still yield the same result.
Here is the applet. It's very simple.

What does your error console report? - Which one? Browser, PC, ect
How about your java console say? - I have no clue what it could be saying since java.exe crashes the moment the applet starts the console is no longer accessible.
What browser and version? - Firefox v3.6.13
Have you tried a different one? - Yes Ie 6,7, and 8. Though the site the applet runs form was designed specifically for firefox (internal site)
Have you tried Appletviewer? - Yes applet runs as intended.
Did you give the Applet permission? I know you said you signed it - did it all go right? - Yes. Gave me the usual response of will expire in x months

Hi... I have run into the same problem today... and I've found a solution... kind of. I hope it's not too late for my answer. 1) download ShellExView from here: http://www.nirsoft.net/utils/shexview.html#DownloadLinks 2) disable the two items highlighted in the image: The context menu problem will be solved... for a little benefit of (probably) not having those shortcuts for WD utilities in the context right-click menu, but I guess you can still use them elsehow. Hope this helped you. I've found the solution myself and it worked for me.

Java.exe (j2re1.4.0) can't init C:\WINNT\system32\DDRAW.dll

Our app is running on jre 1.3.1_01. When we try j2re 1.4.0 we get the following dialog:
java.exe - DLL Initialization Failed
Initialization of the dynamic link library C:\WINNT\System32\ddraw.dll failed. The process is terminating abnormally.
It occurs when the application attempts to paint the splash screen for our server application. It also occurs with our client GUI.
This is the same for 6 different machines running Windows NT 4.0 service packs 5 and 6.
I don't want to make this a bug yet because it seems to work on my laptop with exactly the same software. We have sync'd the environment and verified the classpaths.

I've seen potentially related problems on NT4-SP6a with J2RE 1.4.2_01. I did not get the "can't init" error that you are discussing, but I have seen other problems related to "ddraw.dll". When I run Swing applications that use viewports, scrolling causes very bad repainting problems. I think this is related to "ddraw.dll" because of the "BIT_BLIT" optimization for repainting.
Also, when I ran the Java application after running some other sequence of applications (I have not been able to duplicate the startup sequence), Java crashed with the message below rather than repainting poorly. This crash was repeatable -- I repeated it four times with identical exception traces. The stack trace indicates that the failure is in "blitWindowGraphics", and the problem was detected inside of "ddraw.dll".
I'm including this in this thred in the hopes that somebody can find a thread of commonality and fix the root cause of these "ddraw.dll" problems.
NOTE: I have not found a workaround to the problems I'm having --- I cannot run Java GUI applications on this PC.
An unexpected exception has been detected in native code outside the VM.

Calling back c++ method in an exe (not a dll) from java?

Hi all,
I have to make an hybrid C++/java from an existing C++
application that compiled is a big single exe not a dll.
I'm running under win32.
The application consists of several windows. The hybrid
will have widows in C++ and some in java. They have the
same menu and tool bar. In the C++, there are some
callbacks called when a button is pressed. How to call
these callback from java given the fact that the JVM and
the java classes are launched by the exe file.
I know how, from C++, start JVM and call my java window.
I also know how to call a C++ method that is in a dll from
java. It's from the tutorial
http://java.sun.com/docs/books/tutorial/native1.1/index.html
But I don't know how to call a C++ method that is in in an
exe which has launch a JVM from an object running in this
JVM.
Is there somewhere an example like this?
Thanks,
Xavier.

Java.exe crashing with Dr Watson access violation at address 500bf974

We have been sucessfully runing an application delveloped with JDK 1.2.2 on a Pentium III machine with Windows NT 4 SP5 (384Mb RAM). I have replaced the Pentium III machine with a pentium 4 with 1Gb RAM (still running NT4 SP5). In fact, I simply took the HDD out of the PIII and installed it in the P4.
All applications work correctly (Sybiz Vision, MS Office 97 suite), however, when I go to run the java application is crashes and a Dr Watson Access Violation in java.exe error is generated.
I have:
1. Reinstalled the JDK 1.2.2.
2. Confirmed that all hardware drivers (new NIC, Video and Sound Card) were updated with the appropriate versions from the hardware suppliers web pages.
3. Read thru previous posts on this site (and others) for similar errors, but have only been able to find similar questions.
4. Lowered the video card display colours to 256 rather than 65,536.
None of the above have made any difference.
I hope this question will prompt the java/Dr Watson gurus out there to help me resolve this frustrating problem.
Thanks in anticipation.
Greg

Consider getting 1.2.2_014, or whatever is the latest version of 1.2.2. I think there were some issues with Pentium IV processors which were fixed in one of the later incarnations of the JDK.
You can get the latest version of 1.2.2 from the following url:
http://java.sun.com/products/jdk/1.2/download.html

Faulting application java.exe, version 0.0.0.0, faulting module jvm.dll,...

We have a customer that has been receiving the following error for the last 6 to 8 weeks (about once or twice a week) while running our application:
Faulting application java.exe, version 0.0.0.0, faulting module jvm.dll, version 0.0.0.0, fault address 0x000449f7
Our application is running on Java 1.4.2_04-b05 and uses Tomcat 4.1.30 (or thereabouts). The OS is Windows 2003 Server. We have many other customers running the application on the same version of Java and Tomcat on a variety of OS versions, but have not seen this problem before.
We have replaced the java .exe's and .dll's to make sure one had not been corrupted, but to no avail.
There is another similar thread that has no resolution already out there:
http://forum.java.sun.com/thread.jspa?messageID=9961112
but I wanted to put some Duke dollars on this post, so I posted it separately.
If anyone has seen this problem and found some way around it (no matter how severe the remedy) please respond.
Thanks.

do you see any core/dump files??

Java.exe crashes with windows access exception

When OracleASHome102HTTPServer starts I get a Win2000 access exception c0000005 on java.exe. Little DrWatson window pops up... O9i logs Logs show nothing. Only drwatson shows problem info, assembler dump, ets...
Anyone know what's wrong? I've got O9iAS 1.0.2.0, Win2000SP1, Pentium 4, 1.4GHz, 512Mg RAM?
I know there is a problem with the jre JIT compiler on the P4. Got around this during O9iAS installation by using the '-nojit' parameter on all invocations of jrew.exe and jre.exe. Is my java.exe problem still with the P4 chip?
Regards,
Jim Anderson

solution
I have solved the problem,and the method as follows:
1.look for the dll file:symcjit.dll(the path is %oracle_home%\Apache\jdk\jre\bin) ,
2.change the extension to .old
3.restart the httpServer
4.ok
try it,and hope you good luck

Difference between java.exe and java.dll

can some one tell me the difference between java.exe under bin directory of jdk and java.dll under bin directory of jre under jdk. and how to determine jre the application is using.How to locate istalled jres in windows registry

can some one tell me the difference between
java.exe under bin directory of jdk and
java.dll under bin directory of jre under jdk.java.dll is the library containing the Java Virtual Machine. java.exe is the
program you execute to run Java. It uses java.dll. The java.dll can also be used
to invoke Java classes from other languages using the Java Native Interface (JNI), see
http://java.sun.com/j2se/1.4.2/docs/guide/jni/index.html for more information.

Java.exe crash on P4 machine

Is anyone aware of issues with running jdk1.2.2_008 or later on Pentium 4 machines?
I installed a app server on Windows 2000 on my home machine and when I try and start it, a Windows popup window appears saying java.exe has generated errors. Where should I look for a more detailed error message?
The software runs fine on my laptop running 2000 and the only major difference I can think of is the Pentium 4 architecture.
Any help appreciated!

Have you found a solution to this problem? I am running java applications on numerous IBM desktops (not P4's)running Windows 2000, but have tried installing JDK1.2.2_006 on a Dell desktop with P4 processor and java.exe aborts with exception nr c0000005 (access violation). I have been cussing Dell, but is it the P4?

BOXI 4 SP2 Patch 11 - Constant awt.dll crashes in the Event Log

This should be a supported configuration so need ideas on why this is happening?

Hi All,
SAP Support finally came through for us on this.
The issue is due to the version of the SAP JVM that comes bundled with BOXI 4 SP2 Patches 11 and 12.
If you download the latest version of the SAP JVM from the SAP support portal and install this instead then the problems are resolved.
Thanks,
Gary

[CS5 Windows] LBQ crashes Java

Hi all,
I'm trying to follow the instructions in the "Working With Load Balancing and Queueing" document for CS5 server. I've run four instances of ID Server using the recommended CORBA parameters in that document. Then I started LBQ by running the "clover.cmd" batch file (after tweaking it a bit, because they forgot to set the JAVA_HOME path). All seems well.
However, when I ping the LBQ as recommended, by opening this URL:
http://localhost:8080/com.adobe.clover.application/api/GetVersion
I get a message that Java has crashed. Specifically, it says "Java(TM) Platform SE binary has stopped working." Then Windows helpfully offers to find a solution (I've never actually experienced Windows finding a solution, ever). Of course then the browser request times out, and we're back to using QuarkXPress.
This is using Windows Server 2008 R2 Standard, Service Pack 1 (say that fast, 3 times), and InDesign CS5 Server 7.0.0.355.
I thought perhaps the Java version was suspect, so I uninstalled it (both 32- and 64-bit versions) and installed fresh versions from www.java.com. Still the same problem. Then I thought, maybe it needs more memory, so I changed the command line -Xmx parameter from 512M to 1024M. Still the same problem.
The problem isn't InDesign Server, because it never actually gets to that point; it's in the LBQ Java code (I think) and/or some mystical Java configuration.
So I'm stumped. Has anyone successfully used Adobe's load balancing solution as documented?
Thanks in advance for any advice.
Regards,
Chuck Weger

Since it refers to "dt_socket.dll," I thought perhaps there was a firewall issue, so I made sure port 8080 was opened (even though since I'm pinging localhost, I think it doesn't matter). No success.

CoreFoundation.dll crash followed by iTunes Stops Working on Win7 x64

Hello
I had a Sony Vaio laptop (64 Bit Win 7 Pro and Office etc) for almost 2 years. After running latest windows updates (I think) iTunes started stopping at launch.
After searching thru support forums and testing various suggestions, I thought my Win 7 installation got old and corrupted and I was already thinking of upgrading my laptop to i5 or i7, I asked my company to renew my laptop. I started installing my new Sony Vaio.
Same problem reappeared
Safari Quicktime all works. Only iTunes crashes.

Hello
I had a Sony Vaio laptop (64 Bit Win 7 Pro and Office etc) for almost 2 years. After running latest windows updates (I think) iTunes started stopping at launch.
After searching thru support forums and testing various suggestions, I thought my Win 7 installation got old and corrupted and I was already thinking of upgrading my laptop to i5 or i7, I asked my company to renew my laptop. I started installing my new Sony Vaio.
Same problem reappeared
Safari Quicktime all works. Only iTunes crashes.
Win 7 64 bit Pro
iTunes 10.4.1.10
On event viewer, on iTunes launch, corefoundation.dll crashes, few secs later, I receive
iTunes.exe
