[graalvm-users] [External] : java.lang.Thread.sleep() supported in GraalVM?

Hi Gilles and Christian,
I'm a bit lost now.
I'm going to try 2 things:
* Migrate my simple Groovy Swing app to pure Java and see if it works.
* Create a very simple Groovy app with no Swing and see if it works.
Do you have other ideas to test?
Best regards, Erix.

I've watched some Groovy on GraalVM tutorials and it seems to be working, but there was no AWT / Swing.
Does it mean that Swing + GraalVM is not a valid option? Or is it because of Groovy + Swing?

It looks like the issue is not with Thread.sleep but Swing/AWT on Windows (specifically sun.awt.shell.Win32ShellFolderManager2$ComInvoker).
I think it's not a good idea to use --initialize-at-build-time, you're likely to get into a lot of such corner cases. In general only code that has been designed for it or has explicit support in native-image works well under --initialize-at-build-time. I would recommend to use --initialize-at-build-time only on specific packages or type for which you know there is a real benefit.
If you really want to initialize everything at build time, maybe you can try to use --initialize-at-run-time=sun.awt.shell.Win32ShellFolder2

Hi Gilles,
Thanks for the quick reply.
Here is the error message:
Error: Detected a started Thread in the image heap. Threads running in the image generator are no longer running at image runtime. To see how this object got instantiated use --trace-object-instantiation=java.lang.Thread. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image runtime by using the option --initialize-at-run-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.
I've tried the option --initialize-at-runtime=java.lang.Thread, without success.

My Groovy code snippet:
@groovy.transform.CompileStatic
class App {
static void main(String[] args) {
// some very simple Swing UI init here
while (true) {
time = LocalTime.now()
label.text = " " + time.format("HH:mm:ss")
Thread.sleep(1000)
}
}
My native-compile command line:
native-image --report-unsupported-elements-at-runtime --initialize-at-build-time --trace-class-initialization=java.lang.Thread --no-fallback -H:ConfigurationFileDirectories=conf/ -cp ".;%GROOVY_HOME%lib\groovy-4.0.9.jar;%GROOVY_HOME%lib\groovy-datetime-4.0.9.jar" displaytime.App
My native-agent command line (works well):
java -agentlib:native-image-agent=config-output-dir=conf/ displaytime.App

Hi Eric,
Yes Thread.sleep() should work in GraalVM native-image.
It would help to know what kind of error you're seeing exactly.

Subject: [External] : [graalvm-users] java.lang.Thread.sleep() supported in GraalVM?
Hi everyone,
I'm totally new to GraalVM.
I've set up the whole environment for Windows this morning.
I'm now trying to natively compile a Groovy app (with neither dynamic nor meta programming).
I've been able to compile it and use the native-image-agent to generate the /conf files.
Now I'm trying to generate the executable and I get an error message due to the fact I'm using Thread.sleep(x) in my main loop.
Sleep is a static method of the Thread class. I understand there must be some kind of conflicts between the class being initialized at build-time or runtime. But I'm not sure how to fix it. I've spent a lot of time in the GraalVM documentation and several Web sites (stackOverflow, etc.) but could not find a good example of how to use Thread.sleep in GraalVM.
Sorry for the noob question. Any hint would be greatly appreciated. Thanks in advance.
Best regards, Erix.
