The following tooling SW versions are used for my product (named octopus):|
I am developing an e(fx)clipse E4 RCP application featuring a test automation framework. I am using the recommended eclipse tycho folder structure and running the product with Eclipse IDE works fine. However, after successful maven-tycho build, running the application (octopus.exe) fails with the following exception:
Exception in Application start method
java.lang.RuntimeException: Exception in Application start method
Caused by: java.lang.IllegalAccessError: class org.eclipse.fx.ui.workbench.fx.services.InteractiveStartupService (in unnamed module @0x331144b3) cannot access class com.sun.javafx.tk.Toolkit (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.tk to unnamed module @0x331144b3
at javafx.graphics/com.sun.glass.ui.win.WinApplication._runLoop(Native Method)
... 1 more
The exception shows that the unnamed bundle (my octopus application bundle) cannot access type 'com.sun.javafx.tk.Tooljit' because
the module javafx.graphics does not export package 'com.sun.javafx.tk' to the unnamed bundle.
How can this restriction be resolved? How can the 'com.sun.javafx.tk' javafx package get exported to my unamed bundle? I tried to fix it
with all kinds of '--add-exports' '--add-reads' and '--add-modules' vmargs in the octopus.ini, however, without success.
It looks like that these arguments are ignored by the native e(fx)clipse launcher.
I use the type Toolkit in order to synchronize my splash screen and turn it into a startup-dialog. By means of the StartupProgressTrackerService
the splash is hidden and replaced by the startup-dialog.
See uploaded files for parent pom.xml, product.xml, target.xml, generated octopus.ini and config.in.
I am looking for a solution for days . I would appriciate it very much when somebody could help.

We are actually migrating our e(fx)clipse application to openJDK11 & openJFX11. Ran into several similar issues. Please see the attached files (I renamed them to eclipse_man.ini and eclipse_org.ini, resp) which work for us (openJDK11 is located under "C:\Program Files\Java\jdk-11.0.6+10", openJFX11 is located under "C:\Program Files\Java\javafx-sdk-11.0.2"). Also note that NO Windows environment variables are needed for this, at all. The eclipse launcher takes all params correctly from the "eclipse_man.ini" file if the content is correct.|
BUT I have to admit that our "eclipse_man.ini" file is currently created MANUALLY due to several issues:
(1) Somehow during the build all spaces and slashes in the "--module-path" declaration are wiped (so when declaring "C:\Program Files\Java..." as VM argument in the RCP product configuration, we unfortunately get "C:ProgramFilesJava..." in the eclipse_org.ini).
(2) It seems like there is currently no way for declaring the JDK path (i.e. "-vm" parameter) via product configuration (we would like to specify the exact JDK path for each of our application releases so that e.g. different versions can be used in parallel).
Due to these issues, we currently take the "eclipse_org.ini" (original output from the Tycho build) and have to adapt it to "eclipse_man.ini" (which can then successfully start our application).
Hope this helps a bit.
