Subject: [bug#41360] [PATCH v2 9/9] gnu: java-openjfx-web: Add new variable.

From: Alexey Abramov <[email-masked]>
Date: Sat, 30 May 2020 18:41:23 +0200

* gnu/packages/java.scm (java-openjfx-web): New variable.

We build not only a web component here, but webkit as well. Webkit requires
some extra 3rd party libraries icu, libxml, libxslt and sqlite which are
already in openjfx source bundle.
