When using ut.run(); using the last release i've got this error :

Warnings:

1. test_between_string
   Unsupported annotation "--%test(returns substring from start position to end position)". Annotation ignored.
   at "FOD.TEST_BETWEEN_STRING.NORMAL_CASE;", line 5

I'm using Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production, my NLS is CANADIAN FRENCH
