[Bug 2012837] Re: All versions of the JRE doesn't intall properly, all of them result in java using 100% CPU without exucuting code contained in jar file

[Paul]

It was a VM configuration issue. CPU virtualization extensions were
disabled, and so was kvm, it was actually ruining qemu as hypervisor.
The OS was a little sluggish, but java was so catastrophically affected
that it failed to make it to a single print statement. Quite funny that
a whole collection of entire operating systems were working OK but not
java.

Title:
  All versions of the JRE doesn't intall properly, all of them result in
  java using 100% CPU without exucuting code contained in jar file

Status in java-common package in Ubuntu:
  Invalid

Bug description:
  To reproduce:
  1 - Install Ubuntu 22.04 in a KVM virtual machine (can be minimized or not, failed with both)
  2 - sudo apt install default-jre-headless

  The install doesn't complete because cleanup of jar file used in
  hooks. Will hang at 100% CPU usage on a single core until killall java
  -9

  Running any jar results in the same behavior, maximum usage on one
  thread, until killed.
