Could it be related to #103322 @eiriktsarpalis ?

[eiriktsarpalis]

Here is the diff between expected and actual documents:

It would seem that custom attributes on the declaring type are being returned in an unexpected order for the case of mono, which is correspondingly changing the order of derived types in the anyOf array. This results in a syntactically different JSON document but a semantically equivalent JSON schema.

I can't think of a good way to fix the test other than temporarily disabling it in mono. @vitek-karas @lewing is the attribute ordering a known issue and do you have any alternative suggestions?

[lambdageek]

I don't think the custom attributes APIs guarantee a particular order. The order could change even for CoreCLR from one release to the next.

The Json schema exporter should order the custom attribute values into a deterministic order if that is important. Otherwise the schema comparison operation in the testsuite should allow for anyOf to be unordered when doing its comparison
