I already used java 8 with tomcat 9 in intellij and I haven't found any issue.
If you can lunch your tomcat successfully without deploying you app via tomcat startup command and without intellij, so your tomcat is well configured. If not:
Check you environment variables: make sure that you specified jdk1.8 in JAVA_HOME and PATH variables.
Check that your app is also compiled with java 8.
Try to deploy your war on tomcat without intellij to check if it is
really intellij configuration pb
In other hand, I agree with Level_Up that you have to upgrade the tomcat version for security reason as it is too old version.

jaxb-core and jaxb-impl jars are properly added in the project.

The jaxb-core is depending on the istack-commons-runtime, which can be found in the pom of the jaxb-core. (https://mvnrepository.com/artifact/com.sun.istack/istack-commons-runtime)

JavaFX Scene Builder 2.0 Segmentation Fault

JavaFX was working, but strangely, it throws Segmentation Fault (core dumped) now.
I don't know where the logs are kept, so I have launcher app/SceneBuilderApp.jar, just in case:

Environment
Ubuntu 16.04
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)

I had the same problem as you did.
As in the thread already mentioned this seems to be a kernel bug. Updating Ubuntu as usually + running dist-upgrade did the trick for me.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
See here for information what dist-upgrade does.
