问题
Having finally got kettle to start and not hang, I still cannot use it to much avail, as when I try to create a new Database Connection (after creating a new Transformation) I get this error:
org.pentaho.ui.xul.XulException: java.lang.reflect.InvocationTargetException
Thereafter, I get this more general error for the same actions:
General error in dialog
In order to get the first 'java...TargetException' again, I have to close and restart kettle.
Note, this also happens when I load an existing kettle job and try to edit its database connection.
Could this be a configuration issue? A missing or misplaced file ? What is the Target that is failing to be Invoked? Thanks in advance for your help.
My config:
macos 10.12.6 (Sierra)
Pentaho Data Integration (or kettle) 7.1.0
java version "9.0.4"

As I found out from the Pentaho Data Integration forum, it was a matter of my version of Java.
I uninstalled Java 9 and installed Java 8 and then no longer got this error.

There is a .kettle directory in your home directory. In this directory, you may have a db-cache-<some.numbers> file. If that is the case: stop spoon, delete the db-cache file, and restart spoon.
If it doesn't work, an other file in that directory may be corrupted.

As mentioned in Pentaho Components Reference, Only Java 8 is supported by Pentaho Data Integration, So it is not recommended to try out Java 9 or Java 11 at the moment (until they release a version which supports above Java 8).
