The results screenshot test-java1.8.0_212.png shows how it fails to
render the image. test-java1.8.0_162.png shows success on the original
18.04 version of the JRE. Note, in all cases if I specify an image file
that does not exist, all version properly render a JLabel of appropriate
size. So, it would seems that the bug exists after the image file is
successfully loaded.

Title:
  JLabel does not render image in HTML tags

Status in openjdk-8 package in Ubuntu:
  New

Bug description:
  The example program creates a JLabel with text set to "<HTML><IMG
  SRC='file://path/some-file.png'></HTML>". On previous versions of the
  openjdk-8-jre, this would work and the PNG was displayed in the
  JLabel. On the current version, 8u212-b03-0ubuntu1.18.04.1, all that
  is rendered is a tiny label with no apparent image inside. I have run
  the same class file on a RHEL 7 system with JRE 1.8.0_201, and on the
  original 18.04 JRE 1.8.0_162 and it works as expected. I believe this
  also worked correctly on 8u191-b12-2ubuntu0.18.04.1.
