Oxygen crashes on Mac OS X

[Wolfhart]

Hi,

I am running Oxygen 8.2 on Mac OS 10.4 and J2SE 5.0. Sometimes, Oxygen crashes (it quits) for no apparent reason, for example when opening a file that opened without problems earlier on and that opens again without problems after relaunching Oxygen. In the last days, these crashes have become so frequent that I can no longer ignore the problem. Does anyone know what may cause the crashes and how I may solve the problem? Also, is there a way to find out which files were opened when Oxygen crashed? (When relaunching Oxygen after a crash, it does not reopen the files but starts as a blank slate.)

Thanks,
Wolfhart

Hello,

Can you remember what updates or applications you installed before the crashes started to be more frequent?

Do you have the latest Java update and the latest security updates installed on your Mac OS 10.4 machine? If not please install them.

Do you have the accessibility features of OS X enabled (in System Preferences -> Universal Access, specially Voice Over)? Please disable the accessibility features when you run Java applications on your Mac machine.

If these tips do not stop the crashes please post a fragment of the crash log where we can see the thread that crashed and the stack trace of the thread that crashed.

Sorin

Sorin,

Thanks for the reply!

> Can you remember what updates or applications you installed before the crashes started to be more frequent?

I have not installed any updates or applications recently, and I cannot remember when Oxygen crashed for the first time.

> Do you have the latest Java update and the latest security updates installed on your Mac OS 10.4 machine?

The Software Update feature of Mac OS does not offer any new updates (apart from iTunes and Safari, which I refuse to install).

All accessibility features are disabled.

Please find below the relevant fragment of the crash log:

Does this help?

Do you get a crash if you start Oxygen with a command

Code: Select all

sh oxygenMac.sh

executed from a command line in the Oxygen install folder? Is an error displayed in the command line console in case you get a crash? Is the crash log similar (the same crashed thread, a similar same stack trace of the crashed thread)?

No, Oxygen starts normally and seems to function normally.

In that case replace the file Oxygen.app/Contents/MacOS/JavaApplicationStub with the file /System/Library/Frameworks/JavaVM.framework/Versions/Current/Resources/MacOS/JavaApplicationStub and start Oxygen again by double clicking on the Oxygen icon. You can open Oxygen.app/Contents by Cmd+clicking on the Oxygen icon and selecting Show Package Contents. Does Oxygen start up normally now?

[Wolfhart]

Yes, Oxygen starts up normally after replacing the said file and seems to function normally.

Thanks,
Wolfhart

[sorin_ristache]

I don't understand how the JavaApplicationStub was corrupted somehow but replacing it with a local version available on the computer where Oxygen runs is a solution in such cases.

Alright. Thanks, Sorin!
One more thing: Do you know the answer to the other question I asked in the original post: Is there a way to find out which files were opened when Oxygen crashes?
Wolfhart

[sorin_ristache]

No, it is not possible to know the files that were opened at the crash. You can know only the files that are opened when the application is closed normally.

What is your Java version? You can find it in the java.vm.version property in the Help -> About dialog of Oxygen, the System properties tab. Can you send us your JavaApplicationStub file in order to compare it with our file to see the differences?


Thank you,
Sorin

[sorin_ristache]

Thank you for the file. We may include the latest JavaApplicationStub (from Java 1.5.0_13) in future distributions of Oxygen. It is handled better by the new versions of Apple's Java virtual machine.


Thank you,
Sorin
