Re: [orca-list] Eclipse 3.6RC3 seems to be very unstable with orca

I just tried the OpenJDK incase there is something specific in the SunJDK which causes this but I still get the crash.

I will go and file a bug with eclipse (any tips on how to do it), I just thought due to the high number of crashes I get it couldn't normally get through like this and so may be it was something due to having accessibility/orca running. From what you say accessibility isn't the cause.

I don't think that this can be cause by orca.
I am not running java from sun, insted I am running java from ibm and my distro is ubuntu 10.04.
Perhaps this can make some difference.
I think that you should open a bug in eclipse bugzilla.

As an example of how unreliable this seems, in the last five minutes I have just had at least three crashes. I managed to catch what was output to the console while running the SWT snippet(212). I attach the logfile the following refers to.

I am using debian unstable, but eclipse 3.6RC3 is the tarball from the eclipse website. Orca is from GIT, pulled last night (a matter of hours old).

Any more thoughts?

BTW: Accessibility in general seems to be quite improved in 3.6RC3, its just such a shame it crashes as often as it does for me, rendering it useless.

Hi Michael
I am using eclipse 3.6 rc3 on my day job without big problems.
What distro are you using?
What version of orca?
What java VM?

In my opinion this is the more stable version of Eclipse that I've used with the orca.

I have noticed that when using eclipse 3.6RC3 (other SWT applications using SWT3.6RC4 seem to also exhibit this) seem to be very unstable while running orca (I don't know whether it is due to orca/accessibility running, but I doubt such unreliability could be accepted by the large eclipse user base).

I haven't noticed a exact way of causing eclipse to crash, but as it happens so frequently I will give what actions seem to be able to cause the crash. Open eclipse and choose a source file and enter the source code editor. Now just cursor around (generaly less than a minute), for me it will crash very soon, but I can't give any specific movement to do to cause one.

I also notice it for some of the SWT Snippets when using SWT 3.6RC4 (eg. Snippet212 "embedding images in StyledText" will also crash when cursoring around its StyledText control while having orca running).

Is this an orca issue, are we doing something to crash eclipse or is it something in SWT?

Does anyone else notice this? I never had this sort of issue with earlier versions of eclipse (in fact I am unsure whether I have ever had an eclipse crash until I tried eclipse 3.6RC3).
