Core: ServiceOptions.setCredentials fails with ClassCastException when using UserCredentials

[vladimir-lu]

On line

java-core/google-cloud-core/src/main/java/com/google/cloud/ServiceOptions.java

Line 221 in 6aa4476

this.quotaProjectId = ((ServiceAccountCredentials) credentials).getQuotaProjectId();

the check is instanceof QuotaProjectIdProvider but the cast is to ServiceAccountCredentials therefore you get

class com.google.auth.oauth2.UserCredentials cannot be cast to class com.google.auth.oauth2.ServiceAccountCredentials (com.google.auth.oauth2.UserCredentials and com.google.auth.oauth2.ServiceAccountCredentials are in unnamed module of loader 'app')

The cast needs to be changed. google-cloud-core version 1.92.0

Thanks for finding this and reporting it! It's definitely a bug and we'll fix and push a release.
