The high level logic seems reasonable to me, still trying to get a better understanding of the id-token workflow. I will give it a second try after I do some readings on the context.

Maybe something like idTokenWithAudience_oauthFlow_incorrectAudience() to be more specific on the test?

Sounds good, will update!

LGTM.
only a few nit picks.
| String assertion = | ||
| createAssertionForIdToken( | ||
| jsonFactory, currentTime, tokenServerUri.toString(), targetAudience); | ||
| createAssertionForIdToken(currentTime, tokenServerUri.toString(), targetAudience); |

For readability, perhaps rename tokenServerUri tooauthIdTokenUri in parallel to iamIdTokenUri?
| URI iamIdTokenUri = | ||
| URI.create( | ||
| String.format( | ||
| OAuth2Utils.IAM_ID_TOKEN_ENDPOINT_FORMAT, getUniverseDomain(), clientEmail)); |

nit: Can we be consistent with iamIdTokenUri and tokenServerUri? either both declare as class variable or both inside respective get endpoint method.

tokenServerUri is a customizable from setters and can't be declared as a class variable. iamIdTokenUri probably can be initialized in the constructor and I'll move it up there.

On second thought, getUniverseDomain() throws an IOException and adding a checked exception to the constructor is a breaking change. I think it would be better to leave it here.
