I would not trust that list as the definite guide. I just looked for a
random method (which I was just working on for GNU Classpath)
Toolkit.getSystemSelection() and it was not listed.

I don't really like the numbering. I would propose to actually name the
tests with somewhat meaningful names. Something like
<PermissionClassName>_<ClassName>_<MethodName> for each Permission and
class.method() needing to check for that permission. (example:
AWTPermission_Toolkit_getSystemSelection)

Or maybe have a directory per PermissionClassName.

That is how jacks is setup. It follows the JLS, but it doesn't use the
section numbers, but logical names of the sections that the tests are
for.

Cheers,

Mark
