These conflicts were simply hunks that failed to apply because the surrounding context did not match due to later changes in the internal implementation that are not present in JDK11. Since the patch being backported wholly replaces or removes these implementations anyway, my resolution was to simply remove the old implementation and accept the new implementation from the backport patch.
