Examples with ServiceConfigurationError java.util.ServiceConfigurationError used on opensource projects

Example 1 with ServiceConfigurationError

use of java.util.ServiceConfigurationError in project hadoop by apache.

the class TestCluster method testProtocolProviderCreation.

@Test
@SuppressWarnings("unchecked")
public void testProtocolProviderCreation() throws Exception {
    Iterator iterator = mock(Iterator.class);
    when(iterator.hasNext()).thenReturn(true, true, true, true);

    Cluster testCluster = new Cluster(new Configuration());
    // Check that we get the acceptable client, even after
    // failure in instantiation.
    assertNotNull("ClientProtocol is expected", testCluster.getClient());

Example 2 with ServiceConfigurationError

use of java.util.ServiceConfigurationError in project lucene-solr by apache.

the class NamedSPILoader method reload.

   * never removed or replaced.

   * of new service providers on the given classpath/classloader!</em>
