[Thomas Schweikle]

It is not fixed as of 13th, Oct. 2020. Same as before. pdfsam basic
crashes while trying to load libraries from openjfx. Regardless it is
installed or not. There are missing libraries. And it turns out missin
are those from openjfx.

Title:
  openjfx is missing native libraries for webkit and media

Status in openjfx package in Ubuntu:
  Fix Released
Status in openjfx source package in Focal:
  Confirmed

Bug description:
  [Impact]
  OpenJFX's media and webkit native libraries are missing from amd64 builds in Focal and Groovy. This is a regression from Bionic.

  This prevents applications that depend on these libraries from working
  correctly.

  [Test Case]
  The libjfxmedia.so and libjfxwebkit.so should be present in the libopenjfx-jni binary for all archs.

  One can see in the amd64 package listing for Focal [1,2] and Groovy
  [3,4] that libjfxmedia.so and libjfxwebkit.so are only available on
  arm64, armhf, ppc64el, and s390x.

  [1] https://packages.ubuntu.com/search?searchon=contents&keywords=libjfxmedia.so&mode=exactfilename&suite=focal&arch=any
  [2] https://packages.ubuntu.com/search?searchon=contents&keywords=libjfxwebkit.so&mode=exactfilename&suite=focal&arch=any
  [3] https://packages.ubuntu.com/search?searchon=contents&keywords=libjfxmedia.so&mode=exactfilename&suite=groovy&arch=any
  [4] https://packages.ubuntu.com/search?searchon=contents&keywords=libjfxwebkit.so&mode=exactfilename&suite=groovy&arch=any

  Another possible test case is running pdfsam in the console to split a PDF file (after pdfsam bug 1887142 is fixed) and look if errors as:
  Caused by: java.lang.UnsatisfiedLinkError: no jfxmedia in java.library.path: [/usr/java/packages/lib, /usr/lib/x86_64-linux-gnu/jni, /lib/x86_64-linux-gnu, /usr/lib/x86_64-linux-gnu, /usr/lib/jni, /lib, /usr/lib]
  show up in the stdout. A sound should be played if everything works.

  [Regression Potential]
  Enabling the native libraries will allow applications to use them again.
  * This can trigger errors in applications that hidden by the fact that there were no native libraries to use.
  * This can cause applications that use OpenJFX to fail to run or crash during runtime.
  It is unlikely that autopkgtest will detect such errors given that OpenJFX _did_ migrate when the native libraries were missing (and that should have caused errors).

  [Other Info]

  [Original Report]
  I'm trying to run BlueJ on Ubuntu 20.04 (fresh install), while the main app runs the editor refuses to start, looking at its logs apparently it can't find jfxwebkit. So I tried to search for it, and apparently it is present in the other architectures for Focal as well as all architectures in Eoan, Bionic and Xenial in the libopenjfx-jni package, but not for Focal amd64. The version of openjfx I have is 11.0.7+0-2ubuntu1. I have also attached BlueJ's log for reference.
