Original commit does not apply cleanly due to the options "-Xlog:class+load+cause" "-Xlog:class+load+cause+native" were not added until a later [version](https://bugs.openjdk.org/browse/JDK-8193513), thus these cases are excluded. Some args in exec() also were not added until a [later version](https://bugs.openjdk.org/browse/JDK-8289184), thus they are excluded. Additionally, [these flags](https://bugs.openjdk.org/browse/JDK-8256718) were deprecated in a later version and thus removed from this test; simple modifications are added so that these later removed cases follow the backport logic. Affected test passes.
