This one-test-specific conditional feels a bit icky in an otherwise generic script 😞
Our test framework wasn't really built with this kind of thing in mind, and it's really showing its age 😭

Does pattern matching work when == is used with [ ]? I've always read the bash(1) man page as saying that that pattern matching was employed with [[ ]].
[[ expression ]]
…
When the == and != operators are used, the string to the right of the operator is considered a pattern and matched according to the rules described below under Pattern Matching, as if the extglob shell option were enabled.
Rereading, the comma makes it a bit ambiguous as to whether it is saying the == enables Pattern Matching at all or Pattern Matching with extglob enabled.

Seems like the double square brackets are needed:

This feedback is still unresolved -- I'm not sure what to suggest, however.

This should help us catch bugs like adoptium/containers#415 in the future.
This could be made an OpenJDK-specific test but I figured there is likely no harm running it for all images
