I didn't notice those. It can't be run by any standard task.
TEST.groups has it under
# Just-In-Time compiler tests
vmTestbase_vm_compiler = \
  vmTestbase/vm/compiler \
  vmTestbase/jit \
  vmTestbase/vm/jit

but I can't find anything that runs vmTestbase_vm_compiler
Also it is HEADFUL and no hotspot tests run today in such a mode.
So I am sure it isn't run on a regular basis. I'll file a hotspot bug on this, but first
I'll ask if anyone knows about it.

That was on "my list" at some point - I lost it ! I will update it.

These tests are run in tier1. They don't really use the applet api. They just have some data
in the test directory that they work on that lists java.applet as a package name.

The tests pass so I don't think I need to do anything, but it is probably still worth filing a bug to
see if the owners want to remove applet from the package-list

Will do.

I know about the last 3 and left them.

The demos previously had applet options removed. Some comments must have been missed
I will update.

I saw that one. It wasn't clear to me how it was used, and since I didn't see any test failures I left it.
Another one to file a component team bug about.
