I’d be more than happy to do that ☺
Ideally at a bar at the beach with a nice selection of hops-smoothys ;-)
But for now, assuming you are using IntelliJ and Maven:
All I do, is select “clean” and “install” in the maven tab, right-click and
select “debug”. Additionally in the debugger tab, I click on “edit-breakpoints”
and add a new “Java Exception Breakpoint” and define the class
“java.lang.NullPointerException”. Then the execution will halt exactly where a
NullPointerException is thrown.
But beware … there might be quite a number of NPEs to step though.

No idea what this even means. ;-)
I’d really like to sit down with you while we’re in Miami and see how you
are setup to work on the compiler. I really wish I was more capable of
debugging this stuff… :-(
