| Re: [e4-dev] Blank window for RCP using compatibility package on Linux with Java 1.6 |
Pablo-That is exactly what happened. If the osgi service cannot start (communicate with) a bundle after 5 seconds the process is abandoned and the bundle marked within the osgi runtime. " timed out waiting (5007ms) " I would recommend going through all of your code and eliminating everything from your bundle start() methods. As you experienced, the bundles do not complete the loading process until that method returns (including any classes in the bundle namespace!). If it is absolutely necessary to start some kind of service that may take any length of time, I would recommend creating a job and starting the service that way.JDOn Mon, Jul 16, 2012 at 2:44 PM, Pablo Leite <wpl020@xxxxxxxxxxxx> wrote:
Hi,
Not-working VM is OpenJDK 1.6.0_24, working VM is OpenJDK 1.7.0_03. We didn't try an incremental approach.
I was not able to find the plug-in org.eclipse.e4.tools.emf.ui, our product is based on features. Adding required features didn't fix the problem.
After pressing Alt+Shift+F9 under window there's only a Trimmed Window with ID "IDEWindow".
We were able to make it work by moving an API call from the Activator start method to a Workbench WindowListener, found the tip at http://www.eclipsezone.com/eclipse/forums/t114596.html. Waiting for the workbench to load prior to the API call fixed the problem. We suspect that it was caused by the plug-ins loading order. Looks like we were trying to access a code inside a plug-in that was not fully loaded, and the operation timed out, please have a look at the stack trace below:
!ENTRY org.eclipse.osgi 2 0 2012-07-13 14:37:03.824

Pablo-Could you provide a little more information, specifically what are the build numbers of the JVM's you are using (both working and not-working).Also, have you tried any kind of incremental approach, as in it works for features x & y and x & z but not x, y, & z?Lastly, if you include org.eclipse.e4.tools.emf.ui (make sure you 'Add Required Plug-ins') and press Alt+Shift+F9 what is listed under windows?Thanks,JDOn Fri, Jul 13, 2012 at 2:14 PM, Pablo Leite <wpl020@xxxxxxxxxxxx> wrote:
_______________________________________________Hi,
We are using the compatibility layer to run our RCP on Eclipse 4.2. Everything works fine on Windows and Mac OS-X, however on Linux (Ubuntu 12.4) and java 1.6 all we got is a blank window with the Eclipse SDK title.
If we change the java to java 1.7, the RCP works fine, which is strange since there's no dependency on Java 1.7.
In order to enable the compatibility mode on our product we've added the features below to the product definition:
org.eclipse.emf.ecore
org.eclipse.emf.common
And the following plug-ins as dependency
org.eclipse.e4.ui.workbench,
org.eclipse.e4.ui.workbench.addons.swt,
org.eclipse.equinox.ds,
org.eclipse.equinox.event,
org.eclipse.ui.forms
Some properties also had to be added to the product's plugin.xml file in order to make css themes work:
<property
name="applicationXMI"
value="org.eclipse.platform/LegacyIDE.e4xmi">
</property>
<property
name="cssTheme"
value="org.eclipse.e4.ui.css.theme.e4_default">
</property>
<property
name="applicationCSSResources"
value="platform:/plugin/org.eclipse.platform/images">
</property>
Are we missing something? Is this a possible e4 bug? We just have no clue on how to solve this problem.
Thanks,
Pablo.
