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.

Hi, I would like to add in further information about above problem and I hope someone can tell me the solution to make it work again. Please see image as per the latest error I am getting: https://ibb.co/eR1cep I'd also like to add that I have deleted the .project folder in Eclipse and so I am not sure if this has cause all the havoc I am experiencing now.
