illustrate ReflectionUtils don't generate memory leak
Key: HADOOP-8605
URL: https://issues.apache.org/jira/browse/HADOOP-8605
Project: Hadoop Common
Issue Type: Bug
Components: test
Affects Versions: 1.0.3
Reporter: Yang Jiandan
TestReflectionUtils.testCacheDoesntLeak() uses different urlClassLoader to load
TestReflectionUtils$LoadedInChild by a for cycle:
int iterations=9999; // very fast, but a bit less reliable - bigger numbers
force GC
for (int i=0; i<iterations; i++) {
URLClassLoader loader = new URLClassLoader(new URL[0],
getClass().getClassLoader());
Class cl =
Class.forName("org.apache.hadoop.util.TestReflectionUtils$LoadedInChild",
false, loader);
Object o = ReflectionUtils.newInstance(cl, null);
assertEquals(cl, o.getClass());
}
but every time it generate the same class
