Oracle SQL Developer Problem initializing Welcome Page

Question

I installed the Oracle Sql developer but I am not getting the startup page. A JavaFx error is encountered.

How can I solve this problem?

If you're using OpenJDK there's no need to switch to Oracle JDK (or shoe-horn Oracle's Java FX jars into your OpenJDK installation as has been suggested above); Java FX is now part of OpenJDK but needs to be installed separately:

sudo apt-get install openjfx
