Searching online for similar problems, I found [this issue](https://github.com/OpenLiberty/open-liberty/issues/18043) which suggests upgrading JDT (and specifically the eclipse compiler) might fix it.

Guru had opened an Eclipse bug for JDT explaining our issue [[0]](https://bugs.eclipse.org/bugs/show_bug.cgi?id=574937), there hasn't been a lot of comments on it recently though. Interesting that the update to JDT 3.26.0 fixed the issue for open-library, we're currently consuming 3.18 via 2021-06 [[1]](https://download.eclipse.org/releases/2021-06/202106161001/features/) (and it looks like even through to 2021-12 the same version will be used).
