 A small clarification/correction:
 
 The environment variable above
 will work if you pass the `jpda` command 
 to
 catalina.bat.  If you are not doing that then you need to
 specify the 
 `-agentlib` argument
 explicitely.

I just found out that the User Entries where bootstrap.jar for linking Tomcat to Eclipse is
missing so I added them and it is working 'ok' now.
Not sure why it is not being attached this time round, even with Maven update etc.

Now, the thing that is not working is that the VM I have to repeatedly entered it manually.

It wasn't like that in the past version Tomcat 8.5, 8 etc...

I hope you can advise me how to make it permanently there.   Tks.

The web suggested that I saved it in the common tab in the run configuration Shared File but
even that it is not working
