basic:

"basic" language and library tests. These need run only with File read

permission to read files under "test/script" or subdirs and property read

permission to read properties named "nashorn.test.*"

error:

scripts that should result in compile-time error. The expected files check

for the error message format etc.

currently-failing:

Tests that fail currently - but should pass eventually.

These are excluded for now.

sandbox:

Tests to check that sandbox scripts cannot access security sensitive resources.

Scripts under this directory run with no special permissions other than

what is given to all "sandbox" scripts.

trusted:

These tests run under AllPermission. Put only those scripts that really need

AllPermission - say for eg. creating class loader, full reflective access.
