无法刷新azure java sdk中多个资源的令牌

在通过重定向URL授权后尝试调用两个不同的资源时,第一个调用完成,第二个调用无法使用刷新其令牌 "HTTP 401 Unauthorized"
在下面的代码中,对第二个服务的调用总是失败(即使更改调用顺序或多次调用第一个服务)

ApplicationTokenCredentials applicationTokenCredentials = new ApplicationTokenCredentials(clientId, domain, secret, AzureEnvironment.AZURE);
DelegatedTokenCredentials delegatedTokenCredentials = new DelegatedTokenCredentials(applicationTokenCredentials, redirectUrl, code);
Azure.Authenticated azureAuth = Azure.authenticate(delegatedTokenCredentials);

//First call - resource : https://management.core.windows.net/
azureAuth.subscriptions().list();

//Second call - resource : https://graph.windows.net/
azureAuth.servicePrincipals().list();

经过一些调试,我发现Azure SDK上的以下函数失败: (com.microsoft.azure.credentials.RefreshTokenClient)

AuthenticationResult refreshToken(String tenant, String clientId, String resource, String refreshToken, boolean isMultipleResourceRefreshToken) {
    try {
        RefreshTokenResult result = service.refreshToken(tenant, clientId, "refresh_token", resource, refreshToken)
            .toBlocking().single();
        if (result == null) {
            return null;
        }
        return new AuthenticationResult(
            result.tokenType,
            result.accessToken,
            result.refreshToken,
            result.expiresIn,
            null,
            null,
            isMultipleResourceRefreshToken);
    } catch (Exception e) {
        return null;
    }
}
