Looks like this may have been a false positive as the current changes gives this error:

/home/runner/work/gravitino/gravitino/server-common/src/main/java/org/apache/gravitino/server/authentication/KerberosServerUtils.java:361: error: incompatible types: Charset cannot be converted to String
> Task :catalogs:catalog-jdbc-postgresql:copyCatalogLibs
        throw new IllegalCharsetNameException(StandardCharsets.UTF_8); // won't happen.

It's best to make sure your code can compile before making a pull request.
