I'm afraid these variables aren't related to that bug. Here it another
set of steps that illustrates the problem better than what is given in
the bug. Note that a webapp isn't necessary.
1. Create new Tomcat Runtime and Server.
2. Execute Run -> Run Configurations (or Debug Configurations)
3. Right-click Apache Tomcat and select New
4. Select the Arguments tab and note that the "Program arguments" and
"VM arguments" fields are empty!
The empty "Program arguments" and "VM arguments" fields is the bug.
Executing this launch configuration in its current state is doomed to
fail, as you have seen. To see what should be there, continue with the
5. Click Close to exit the Configurations dialog.
6. Double-click on the Tomcat server in the Servers view to open the
7. In the server editor, click on the "Open launch configuration" link
in the General Information section.
8. Select the Arguments tab and note that the "Program arguments" and
"VM arguments" fields are no longer empty!
The launch configuration is now complete and can be run successfully.
Obviously, step 3 isn't doing something that step 7 is doing. The code
that executes for step 3 needs to include a call to
setupLaunchConfiguration(), or something equivalent, which is what step
7 is doing to set those fields. For Tomcat, it is
TomcatServerBehavior.setupLaunchConfiguration() where the real work is
done to set the values of those fields. Unfortunately, I'm not that
familiar with what actually gets executed in step 3 to say much about
how to hook in the extra handing that is needed.
