The issue you’re experiencing (expected vs actual, screenshot, stack trace etc)

Calling JColorChooser#showDialog() with a Substance L&F active crashes the JVM.

Reproduction steps

1. Load a Substance L&F (I tried both Graphite and Raven).
2. Call JColorChooser#showDialog().

Expected behavior

The color chooser dialog should be displayed.

Actual behavior

The JVM crashes (see log).

Additional information

I created an MCVE to demonstrate this issue. The actual code to trigger the crash is pretty straightforward:

public static void main(final String[] args) throws Exception {
    SwingUtilities.invokeAndWait(() -> {
        try {
            // commenting out the next line will prevent the JVM crash
            UIManager.setLookAndFeel("org.pushingpixels.substance.api.skin.SubstanceGraphiteLookAndFeel");
            JColorChooser.showDialog(null, "Choose Color", Color.BLACK);
        } catch (final Exception e) {
            e.printStackTrace();
        }
    });
}

As the comment suggests, using the default L&F (Nimbus in my case), produces the expected behavior.

Substance 1.5-SNAPSHOT

The same actual behavior occurs when I use Substance 1.5-SNAPSHOT.

OpenJDK JRE on Linux

If I build and run the MCVE using OpenJDK JRE 1.8.0_181, the JVM does not crash, and the color chooser dialog is displayed. However, the resulting dialog appears to be frozen and does not respond to any user input:

Oracle JRE on Windows

When running the Oracle-JDK-built MCVE artifact on a Windows x86_64 box with Oracle JRE 1.8.0_191, the color chooser dialog is shown and behaves as expected.

Final thoughts

I realize there may be a legitimate Linux-specific JVM bug that needs to be fixed here because the JVM should never crash. However, my guess is it would be easier for the Radiance team to report this bug as it seems to be triggered by something Substance is doing.

If there is a Substance-specific change that could be deployed (or some workaround I could employ from application code) to mask the JVM issue, it would be greatly appreciated.

The workaround is to call SubstanceCortex.GlobalScope.setUseDefaultColorChooser()

This should be fixed now. Thanks for testing on multiple configurations.
