Example 2 with PinpointURLClassLoader

use of com.navercorp.pinpoint.bootstrap.PinpointURLClassLoader in project pinpoint by naver.

the class PinpointURLClassLoaderTest method testOnLoadClass.

@Test
public void testOnLoadClass() throws Exception {
    PinpointURLClassLoader cl = new PinpointURLClassLoader(new URL[] {}, Thread.currentThread().getContextClassLoader());
    try {
        cl.loadClass("test");

    } catch (ClassNotFoundException ignored) {
    }

    //        } catch (ClassNotFoundException e) {
    //
    //        }
    // should be able to test using the above code, but it is not possible from bootstrap testcase.
    // it could be possible by specifying the full path to the URL classloader, but it would be harder to maintain.
    // for now, just test if DefaultAgent is specified to be loaded
    Assert.assertTrue(cl.onLoadClass("com.navercorp.pinpoint.profiler.DefaultAgent"));
