To Reproduce

I don't have a minimal reproducer yet sadly.

Expected behavior
No crash.

Screenshots
Not really applicable.

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)

Ubuntu 23.04, GTK 3.24.37

3. JRE/JDK version

JustJ Adoptium OpenJDK Hotspot JRE 17.0.7, Eclipse 4.27.0

Workaround (or) Additional context

Couldn't find a workaround yet.

[torokati44]

It appears that setting GTK_THEME=HighContrast in the environment works around this crash. It might be specific to the "Yaru (dark)" theme in Ubuntu.

[SyntevoAlex]

Could you please also attach the generated hs_err_pid*.log file? It's created whenever JRE crashes.

By the way, how did you manage to obtain a GDB stack trace? When I want that, I have to resort to complicated script that ignores JRE internal exceptions but not the "fatal" exceptions

[torokati44]

Tomorrow perhaps.
I added -Xint to the JVM args in eclipse.ini. This disables the JIT compiler (switches to pure interpreter mode), which uses SIGSEGV.

Somehow this idea never crossed my mind. Thanks!

Let me know if you need any other part of that file.

Thanks for the Java stack.

For some reason, gtk_css_style_get_value (style, GTK_CSS_PROPERTY_BOX_SHADOW) seems to return NULL:

'gtk/gtkcssshadowsvalue.c'
	Line 318
		void
		_gtk_css_shadows_value_get_extents (const GtkCssValue *shadows,
											GtkBorder         *border)
		{
		  guint i;
		  GtkBorder b = { 0 };
		  const GtkCssValue *shadow;
		  gdouble hoffset, voffset, spread, radius, clip_radius;

		  g_return_if_fail (shadows->class == &GTK_CSS_VALUE_SHADOWS);		// <--- Line 327

I have checked crash database for our product (it's based on SWT without Eclipse) and it has exactly zero crash reports like this. So it seems that some special conditions are needed.

I guess that some repro steps would be needed to proceed here.

Alright, I wanted to spare you of it, but here is a reproduction procedure:

In a basic, fresh Ubuntu 23.04 installation (in a VM for example):

• Download this pre-release build of OMNeT++ 7.0: https://drive.google.com/file/d/1EOB9cCSyo1ICrBwLCGBOiinwuexnd30t
• Open a terminal wherever you downloaded it to, and execute these commands:

sudo apt install -y pkg-config make build-essential bison flex python3-pip
python3 -m pip install --break-system-packages numpy scipy pandas matplotlib posix_ipc

tar xzf 230627-3194d1c337-omnetpp-7.0.0pre2-linux-x86_64.tgz 
cd omnetpp-7.0.0pre2/

source setenv
./configure WITH_QTENV=no WITH_OSG=no WITH_OSGEARTH=no WITH_PYTHONSIM=no WITH_BACKTRACE=no
make utils

omnetpp

• Click "Launch", keeping the default workspace location
• Close the "Welcome" tab
• In the dialog that pops up, uncheck "Install INET Framework" but keep "Import OMNeT++ programming examples" checked, click "OK"
• Close the 3 introductory tabs ("Getting Started", "At a Glance", "OMNeT++ Samples")
• Open the imported "resultfiles" project
• Doubleclick the "Fifo.anf" file in it
• This instantly crashed the JVM for me

These steps are asking too much. It would be best to come up with simpler (ideally a pure Java/SWT snippet with main method) reproducer. Learning a whole new project details to debug an issue is not something that many will spend their time on.

[torokati44]

These steps are asking too much.

I thought so too, but this is the best I have at the moment...

It would be best to come up with simpler (ideally a pure Java/SWT snippet with main method) reproducer.

Of course, and I was glad that I managed to make one for #678.
I will try to make one for this as well, but it appears to be a lot more difficult.

[torokati44]

While I don't yet have a minimal reproducer, I got a message just before crashing that may or may not be relevant:
Gtk-CRITICAL **: 12:26:40.957: gtk_css_style_get_value: assertion '(((__extension__ ({ GTypeInstance *__inst = (GTypeInstance*) (style); GType __t = ((gtk_css_style_get_type ())); gboolean __r; if (!__inst) __r = (0); else if (__inst->g_class && __inst->g_class->g_type == __t) __r = (!(0)); else __r = g_type_check_instance_is_a (__inst, __t); __r; }))))' failed

[torokati44]

I have good news, and bad news.

The good news is that I managed to get a reproducer snippet that is completely independent of our product, and is only about 80 lines of code (of which only 20 is really interesting).

CrashyEditor.java

package crashyeditor;

import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.ControlListener;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableColumn;
import org.eclipse.ui.IEditorInput;
import org.eclipse.ui.IEditorSite;
import org.eclipse.ui.PartInitException;
import org.eclipse.ui.part.EditorPart;

public class CrashyEditor extends EditorPart {

    // -------- start debugging stuff --------

    static int callDepth = 0;

    void runWithLogging(String label, Runnable r) {
        System.out.println("  ".repeat(callDepth) + "> " + label + " (" + this + ")");
        callDepth += 1;
        r.run();
        callDepth -= 1;
        System.out.println("  ".repeat(callDepth) + "< " + label + " (" + this + ")");
    }

    // -------- end debugging stuff --------

    @Override
    public void createPartControl(Composite parent) {
        runWithLogging("createPartControl " + parent.getSize() + " " + parent.getLayout(), () -> {
            Composite composite = new Composite(parent, SWT.NONE);

            Table table = new Table(composite, SWT.NONE);
            table.setHeaderVisible(true);

            TableColumn column = new TableColumn(table, SWT.NONE);
            column.addControlListener(ControlListener
                    .controlResizedAdapter((e) -> runWithLogging("column.controlResized " + column.getWidth(), () -> {
                        table.setSize(20, 20);
                        composite.setSize(composite.computeSize(SWT.DEFAULT, SWT.DEFAULT));
                    })));

            column.setWidth(10);
        });
    }

    // -------- start filler stuff --------

    @Override
    public void init(IEditorSite site, IEditorInput input) throws PartInitException {
        setSite(site);
        setInput(input);
    }

    @Override
    public void doSave(IProgressMonitor monitor) {
    }

    @Override
    public void doSaveAs() {
    }

    @Override
    public boolean isDirty() {
        return false;
    }

    @Override
    public boolean isSaveAsAllowed() {
        return false;
    }

    @Override
    public void setFocus() {
    }

    // -------- end filler stuff --------
}

The bad news is that this is still an Eclipse plugin, not a standalone SWT application. I tried really hard, but could not get this crash outside of Eclipse yet.

So the new reproduction procedure is:

• Download, unpack, and start the Eclipse PDE (SDK) 4.28 (For example: https://download.eclipse.org/eclipse/downloads/drops4/R-4.28-202306050440/download.php?dropFile=eclipse-SDK-4.28-linux-gtk-x86_64.tar.gz).

• Unpack and import this project into it: CrashyEditor.zip

• Launch it as an Eclipse Application. Make sure to set the GTK_THEME=Adwaita:dark environment variable in the run configuration! Then relaunch as needed.

• In this inner, runtime Eclipse (with the Crashy Editor available), import and open this other project: test.zip

• Start to open the included (empty) .crs files one after the other, spawning Crashy Editors. After a few of them were opened, the JRE should crash. Sometimes this happens, sometimes it doesn't - a couple relaunches of the runtime Eclipse instance might be needed.

I know this is still a lot more convoluted than simply running a short Java program, but I am really having a hard time further reducing it.

[torokati44]

Note that I have edited the above comment multiple times with newer and newer (more and more minimal) versions of CrashyEditor.zip.

[SyntevoAlex]

I will try to have a look at this when I have time. Hopefully, but no promises, next week.

That is, in order to create SWT snippet, display.addListener(SWT.Skin, e -> table.setBackgroundColor(...)) is needed.

However, even armed with this knowledge, I was still not able to make a snippet to reproduce. For some reason, SWT.Skin gets called at slightly wrong time for me.
