      ### Please provide steps to reproduce where possible

      Enter the commands as seen in the cmd output below. Note the "failed to reserve and commit memory" error:

      ### How did you install Java?

      Via a zip download from the Adoptium site.

      ### Did it work before?

      Yes, in Java 17.



      ### Did you test with other Java versions?


      I also tested this in GraalVM EE ('19.0.1+10-jvmci-22.3-b07'. It does appear to be an upstream bug, but I am not 100% sure:
