Eclipse RCP app hang on MACOSX 10.6 [message #525636]

Hello, we have an Eclipse RCP application running perfectly on windows but we cannot make it run on MAC OS X (10.6) with Java 6.
When launching the application in the OSGI console we have:
[Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.10000
and the application hangs indefinitely.
In the OSGI console we can display the status of our ui bundle; it is RESOLVED; and if we start it manually, we can see that the bundle Activator class is executed but the GUI does not show up.

We tried with Eclipse galileo SR1-cocoa-32 and SR2-cocoa-32; but it produce the same result.

- Is there any issue with SWT on Mac OS X ?
- Why do we have the message "CocoaComponent compatibility mode" ?
- We are developping with SWT Designer on windows, is there known problems on Macosx ?
- Could you suggest some options we can try ?

Best regards

Christian

Hi Christian,

> - Could you suggest some options we can try ?

how do you launch the RCP application? The only issue on OS X I can think of is that SWT
on Cocoa requires the Display to be initialized on the main thread. Imho this cannot be
done in a plain OSGi environment using Activators, you have to start such applications
using the 'Eclipse Application' launch configuration type (which works around this issue).
Not sure if that's what's going on in your case, it would be very uncommon not to start an
RCP application as 'Eclipse application', but as you mentioned the OSGi console /
Activator explicitly, I thought it might be worth mentioning.

Greetings,

Ralf

Hi,

the missing values for -os, -ws, -arch, -nl in your eclipse.ini look suspicious, are these
really missing or did they get lost when you pasted the contents?

This is the eclipse.ini as created by the PDE Build when exporting for Mac OS X:

-startup
.../../../plugins/org.eclipse.equinox.launcher_1.1.0.v201003 29.jar
--launcher.library
.../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx. x86_64_1.1.0.v20100322-1720
-vmargs
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts

I'm not sure about the "-XstartOnFirstThread", I think this is Carbon-related, on Cocoa
starting works fine even without this argument for me, but it might not hurt to try it.

Greetings,

Ralf

Hi,

I removed the -os, -ws, -arch, -nl from my eclipse.ini file as there was no supplied values and added the option -XstartOnFirstThread but the behaviuor is still the same: no GUI showing up...

Worth noting the UI bundle is packaged with the following options in the manifest:

Bundle-RequiredExecutionEnvironment: J2SE-1.5
Bundle-ActivationPolicy: lazy
Ignore-Package: org.eclipse.ui
Build-Jdk: 1.5.0_22

Any ideas...

Christian

Hi Christian,

is there any specific UI component that you are using? For instance,
custom components, Nebula widgets or Swing code using an AWT bridge?
Keep in mind that the Cocoa implementation of SWT is fairly new and
might be not completely finished.
You could also try out the Carbon version, if 64-bit is not a requirement.

Alex

Hi Alex,

Yes we are using the Nebula compositetable widget.

I tried out with the Carbon version and it works.

However some widgets does not behave like on the windows platform: for instance the calendar widget has no drop down list.

DateTime birthDate = new DateTime(parent, SWT.BORDER | SWT.SINGLE);

Is there some options to get it like on the windows platform ?

Thanks for your help

Christian.

Hi Christian,

if it works fine with Carbon, you can still deploy your application with it. I
don't think the Carbon implementation of SWT would get deprecated before the
next major release of Eclipse (e4).
As for the Nebula widgets - may be not all of them, but the majority hasn't been
updated in a while, so I wouldn't expect them to be compatible with the new
version of SWT. Moreover, depending on the exact implementation, it's not
unusual that they were built only for Windows (In fact, they used to include the
OS compatibility on the top of the page, but I see this has been removed).
I'm not familiar with the specific settings for every Nebula widget, so I can't
tell you how to fix your problem (or if it is at all fixable) - but you can ask
in the Nebula newsgroup, the chaps over there should have some pointers.

Cheers,
Alex
