I still get an empty palette with Java 17 when I install the latest WindowBuilder plugin in my RCP application with the p2 Update Manager. In Eclipse however it seems to work. The following error is thrown when I open and click on the design tab:

java.lang.NullPointerException: Cannot invoke "org.eclipse.wb.core.model.ObjectInfo.getBroadcastObject()" because "this.this$0.m_rootObject" is null

With Java <16 there was no problem. I also tried a fresh installation with the latest built to no avail.

I can reproduce this error on MacOSX and Windows using
Eclipse Adoptium, java.version: 17.0.1
WindowBuilder version: 1.9.7.202112211354

Hi,

Sorry for that bug... Can you post the whole stacktrace ?
Can you also check if the plugin org.eclipse.wb.core is started ?

In your list of plugins, you have 2 families :

the plugins with version number 1.9.1.202009181620. These plugins correspond to WB 1.9.4 (https://archive.eclipse.org/windowbuilder/1.9.4/)
the plugins with version number 1.9.1.202112211354. These plugins correspond to upcoming WB 1.9.8

Can you please clean/update your configuration in order to use only the latest release of WB ?

I once again cleaned up with the latest built (somehow I reverted the installation to test older versions)
However the same error occurs: design tab stays empty, on-click the error message is printed -
in additon in the console I get a "BurningShell" log message with ASCII Art.

In my configuration I open the following relevant modules in the *.ini file:

--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.desktop/sun.awt=ALL-UNNAMED
--add-opens=java.desktop/sun.java2d.opengl=ALL-UNNAMED

Ok thank you for your feed back.

I'm a bit puzzled by this bug. If you remove the options --add-options is it better ?

No, that doesn't makes a difference. I think the bug is quite similar to the reflection bug for Java 16 which was cured for Eclipse with the workaround.

#45

However this also didn't work for an RCP application.

The last running version was with Java 15.

Unfortunately I don't get an informative error message why the design tab is empty.

I made a fresh install of the WindowBuilder plugin in my RCP and in the workspace logfile a more interpretable error showed up.

Responsible for the error is:

https://github.com/eclipse/windowbuilder/blob/38926a364b1904459d44f6742e7573b76f14ec5d/org.eclipse.wb.core.java/src/org/eclipse/wb/internal/core/utils/reflect/ProjectClassLoader.java#L378

It seems that the 'org/objectweb/asm/ClassVisitor' class can't be found.

Here the complete error message:

Hello Friends,

I have the same problems with "empty palette"

I have the next Eclipse version installed

Eclipse IDE for Java Developers (includes Incubating components)
Version: 2022-09 (4.25.0)
Build id: 20220908-1902
OS: Windows 10, v.10.0, x86_64 / win32
Java vendor: Oracle Corporation
Java runtime version: 18.0.1.1+2-6
Java version: 18.0.1.1

How do I make it show the complete context menu?

thanks in advance for your support!

@MarcelS4 I think this has something to do with the "basic" setting that you introduced? Please take a look at this.

How can the "basic" option be set anyway? I see no preferences for this. Where is this documented?

@wimjongman What do you mean by "basic" settings? Do you mean the the *ini file of the RCP?

I made a new attempt and installed the latest version (Upcoming (1.12.0)). I can now sucessfully open and start the GUI when I create a new project. It seems that the latest library replacements (CGLib to ByteBuddy?) fixed the exception somehow related to the classpath. I found only one new exception with a more complex layout but the bug mentioned here is fixed.
