Illegal access run-time error due to controlsfx's BreadCrumbButton

[hmf]

This is more of a Java modules configuration issue, but I am hoping someone has already encountered this and can point me to the answer.

I have the following error when running a the "ChartIndicatorSample" in my project:

Caused by: java.lang.IllegalAccessError: superclass access check failed: class de.gsi.chart.ui.ProfilerInfoBox$CustomBreadCrumbButton (in unnamed module @0x1ea72a45) cannot access class impl.org.controlsfx.skin.BreadCrumbBarSkin$BreadCrumbButton (in module org.controlsfx.controls) because module org.controlsfx.controls does not export impl.org.controlsfx.skin to unnamed module @0x1ea72a45

According to the controlsfX documentation I have added the following JVM arguments:

            "--add-exports=javafx.controls/javafx.scene.control.skin=ALL-UNNAMED",
            "--add-exports=javafx.graphics/com.sun.javafx.scene=org.controlsfx.controls",
            "--add-exports=javafx.graphics/com.sun.javafx.scene.traversal=org.controlsfx.controls"

I have also added other combinations using the module name org.controlsfx.controls instead of ALL-UNNAMED but with no success.

TIA

https://github.com/GSI-CS-CO/chart-fx#javafx-jvm-command-line-options lists the following

--add-modules=javafx.graphics,javafx.fxml,javafx.media
--add-reads javafx.graphics=ALL-UNNAMED
--add-opens javafx.controls/com.sun.javafx.charts=ALL-UNNAMED
--add-opens javafx.controls/com.sun.javafx.scene.control.inputmap=ALL-UNNAMED

Thanks for the quick replay.

I have already tried this with no success. :-( Note that I am using the chart-fx as a standard library in my project and it works save for the bread-crumb issue.

I am now trying to use the library as a module but I get a module not found (I used de.gsi.chart.chartfx-chart and chartfx-chart). Was hoping this would solve the issue.

I have succeeded in using the chart-fx as a module. But the error is essentially the same - the module is not unnamed now. Here is the error:

Caused by: java.lang.IllegalAccessError: superclass access check failed: class de.gsi.chart.ui.ProfilerInfoBox$CustomBreadCrumbButton (in module de.gsi.chartfx.chart) cannot access class impl.org.controlsfx.skin.BreadCrumbBarSkin$BreadCrumbButton (in module org.controlsfx.controls) because module org.controlsfx.controls does not export impl.org.controlsfx.skin to module de.gsi.chartfx.chart

But I think the export is correct. Here are my arguments:

I have also set the library version to the ones in the Maven POM just in case. Mut be something with the controlsfx parameters.

The ControlsFX piece is just used for the ProfilerInfoBox to some show FPS in the examples. You can try adding

--add-opens=org.controlsfx.controls/impl.org.controlsfx.skin=ALL-UNNAMED

If that doesn't work, maybe it's easier to just ignore the benchmark stats and remove these two lines ChartIndicatorSample.java#L125-L126.

@ennerf

This line nearly worked. I think it is only applicable when chart-fx is not used as a module.

--add-opens=org.controlsfx.controls/impl.org.controlsfx.skin=ALL-UNNAMED

This worked because I used it as a module.

"--add-opens=org.controlsfx.controls/impl.org.controlsfx.skin=de.gsi.chartfx.chart",

I have more issues but I will create a new question if required.

Thank you.
