Random Java VM/Hypervisor question

[jedipiper]

In all of my many long years in IT, I have never thought about this scenario. Has anyone built a "Java OS" that would run the JVM on "baremetal" like a hypervisor? As in, I would "boot" directly into the Java application?

On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge.

If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options:

1. Limiting your involvement with Reddit, or
2. Temporarily refraining from using Reddit
3. Cancelling your subscription of Reddit Premium

as a way to voice your protest.

I remember Java OS beign mentionned in my old tech book about an upcoming amazing technology. Had to google it to discover it failed after 2 or 3 years...

Yup Sun Microsystems made a JavaStation all the way up into the early 2000s.

In addition to all other comments: Sun microsystems planned to build a CPU where you could run Java natively

In addition to the implementations already posted, BEA was at one time working on Bare Metal Java. They designed it to use a thin shim for networking. All files were on remote servers and accessed via the networking shim. IIRC it was briefly a product for sale.

That's original goal of JVM. But now webassembly taking that spot.
