Fix request [17u] I backport this for parity with 17.0.10-oracle. Required folowup of 8308103. Clean backport on top of 8308103. Test passes. SAP nightly testing passed.

Fix request [21u] I backport this for parity with 17.0.10-oracle. After it being backported to 17.0.10-oracle, the risk of bringing it to 21u should be acceptable as this will have much less exposure. Clean backport on top of 8308103. Test passes. SAP nighlty testing passed.
