Null pointer exception when running the MTA Plugin 5.0.1 using Eclipse Version 2020-06.
A workaround to this issue is to use Red Hat CodeReady Studio (12.15) rather than Eclipse

Steps to reproduce:
1. Install Eclipse 2020-06

2. Install the http://download.jboss.org/jbosstools/photon/stable/updates/

Some of the JBoss tools are not compatible with JDK8, so you may need to change the eclipse.ini file to add the property to point to JDK11, in my case I added

*-vm
/usr/lib/jvm/java-11-openjdk-11.0.7.10-0.fc30.x86_64/bin/java
*
That property needs to be added above -vmargs in the eclipse.ini file

3. Add the MTA extension to Eclipse from
https://download.jboss.org/jbosstools/photon/stable/updates/mta/5.0.1.Final/

4. Restart Eclipse
5. Switch to the MTA perspective
6. Import a project
7. Start the MTA server
8. Try to run an MTA analysis
