Redline Smalltalk is the site for a Smalltalk implementation that runs on the JVM, with posts on bytecode and Java integration.
HN commenters point to it as evidence that Smalltalk has been ported to the JVM, though one is unsure of its current status.
two things. First though, please google before getting all dismissive.
1) YES smalltalk _has_ been ported to the JVM https://www.redline.st/ AND you can also run it in the GraalVM https://www.graalvm.org/
2) I'm pretty sure the initial JVM was a clone / extension of a Smalltalk VM. Having trouble googling the details, but while you may be having trouble getting it to work on your particular Windows install you might want to consider that you're possibly ignorant of the fact that the Smalltalk VM is not only one of the best available but battle tested over decades.
I would guess that what you're seeing is a particular windows issue that has nothing to do with the VM itself.
I've worked with Smalltalk for four years now, and for what you write, I guess you haven't been keeping up with our progresses. Take a look at:

http://www.redline.st/
http://pharo-project.org
Saying Smalltalk hasn't kept up with computing progress is an old argument that doesn't make sense anymore.
There's also redline smalltak for the jvm, but I'm not entirely sure of it's status:

[edit: on the subject of performance, and interesting Smalltalks, I'd also recommend checking out Gemstone GLASS:
http://seaside.gemtalksystems.com/
They also made "maglev" ruby:

Not having used them myself, I can't comment on the quality of the JVM based Smalltalks:

Another project that I watched without trying myself was for .NET:
https://refactory.com/sharp-smalltalk/
There was also Essence# but it doesn't seem active.
Here's a little blog post about Redline Java interop

Short story:
import: 'com.friendly.Greeting' as: 'Greeter'.
Greeter new say.
I'd never noticed that it looked like that at a smaller size.
As you can see; he isn't: http://www.redline.st/image/duke-large-404.png
Gives me more impetus to come up with a better logo though.
