### Question:
SpiffeTrustManager extends X509ExtendedTrustManager { @Override public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[0]; } SpiffeTrustManager(@NonNull final BundleSource<X509Bundle> x509BundleSource,
                              @NonNull final Supplier<Set<SpiffeId>> acceptedSpiffeIdsSupplier);  SpiffeTrustManager(@NonNull final BundleSource<X509Bundle> x509BundleSource); @Override void checkClientTrusted(@NonNull final X509Certificate[] chain, final String authType); @Override void checkServerTrusted(@NonNull final X509Certificate[] chain, final String authType); @Override X509Certificate[] getAcceptedIssuers(); @Override void checkClientTrusted(@NonNull final X509Certificate[] chain, final String authType, final Socket socket); @Override void checkServerTrusted(@NonNull final X509Certificate[] chain, final String authType, final Socket socket); @Override void checkClientTrusted(@NonNull final X509Certificate[] chain, final String authType, final SSLEngine sslEngine); @Override void checkServerTrusted(@NonNull final X509Certificate[] chain, final String authType, final SSLEngine sslEngine);  }### Answer:
@Test void getAcceptedIssuers() { X509Certificate[] acceptedIssuers = spiffeTrustManager.getAcceptedIssuers(); assertEquals(0, acceptedIssuers.length); }
