The change was in [the 24u commit](https://git.openjdk.org/jdk24u/commit/81252ef76899ad95197550a11c2786ccf3cf0cd2) which was applied later than the 21u one.

Could we establish whether or not this omission is something we need to fix first? Sorry for the ignorance, but it appears to be some file being used only for generating javadoc in test code?
