![]() ![]() The IndexPreferencesTask doesn't seem to stop.Has anyone else experienced this sort of issue? Also able to resolve it by removing JFX version 11 files? Have I done something daft here that I missed?ĮDIT1: Fixed a typo and I ran my test on Windows 10 as well. What I suspect happened in my initial tests is that since I installed OpenJFX version 11 (as it is the long term support version and matched the OpenJDK version) that there was a run time conflict with the files SQL Developer was expecting (as it ships with and installed under my home directory what appear to be JFX version 12 files – i.e., newer version files). SQL Developer Release Notes (here, as of today, for reference): Also, it seems that since JDK 12 was not a long term support release that the version 12 JFX files are no longer readily available. I do know that I installed OpenJDK and OpenJFX version 11. I don't know for certain if that is an issue. So, it seems possibly suspect that JDK version 11 is needed but JFX version 12 files are shipped. Given the directory name, it seems that these files are JFX version 12 files, though the SQL Developer release notes indicate JDK 11 is needed. Some additional investigation revealed that SQL Developer 19.2 now ships with JFX libraries in the following location:Īs part of the startup process for displaying the Welcome page (and possibly other things too) it appears that SQL Developer now creates this directory underneath the user's home directory and populates it with the required JFX files (if it doesn't already exist). But, not only that, the directory was populated with the various JFX shared libraries. I then ran another strace session with SQL Developer and I could see in the strace output that SQL Developer had created a new directory: I had just removed JFX which is a requirement for the Welcome page. To my surprise SQL Developer opened with no errors and the Welcome page was correctly displayed. Run the following command to install OpenJDK 11. How To Install OpenJDK 11 On Ubuntu 18.04.

In this tutorial, We will learn the method to install OpenJDK 11 in Ubuntu 18.04. usr/lib/x86_64-linux-gnu/jni/libjfxmedia.so Clearly this was not a case of the Welcome page not being able to open but a case of improper display.Īfter a bit of messing around I decided to use strace on a session and I could see that the OpenJFX shared libraries were being loaded from the install location from the above installation step (for example, among several): So, I clicked and, ah ha!, a connection and its corresponding worksheet opened. No errors were reported – just a big white blob of space where the Welcome page content should be.īut, even though it displayed as completely blank, moving the mouse around areas where I knew content to be (such as the recent connections list) caused the mouse to change to the “hover link” pointer. When the Welcome page displayed it was completely blank. Installed OpenJFX (version 11) packages:Īfter installing what I thought were the needed packages (especially OpenJFX since JFX is no longer part of the JDK) I executed sqldeveloper.sh from the location where I had unzipped it.Installed OpenJDK (version 11) packages:.Used the Synaptic Package Manager for the package installations.Ubuntu 18.04 Long Term Support on bare metal machine (i.e., not a VM).SQL Developer 19.2.0.206.2117 (yes, I know there is a slightly newer release as of today but I was lazy and did not test, nor did I test older version).This manifested itself primarily in the Welcome page appearing completely blank and no errors being reported. my searching didn't find it if so.Īs part of a recent exercise wherein I wanted to explore using Ubuntu 18.04 LTS on my desktop I ran into some issues with SQL Developer 19.2 and JFX.
