In the following scene, it will cause a memory leak:
```java
private static final ThreadPoolExecutor TPE = new ThreadPoolExecutor(4,
4,60 , TimeUnit.SECONDS, new ArrayBlockingQueue<>(1000));
public static void main(String[] args) {
// do something
TPE.execute(new Runnable() {
@Override
public void run() {
// do something
}
});
TPE.shutdown();
try {
TPE.awaitTermination(2, TimeUnit.HOURS);
} catch (InterruptedException e) {
// do something
}
}
```
ThreadingMethodInterceptor class, as below：
```java
@Override
public void beforeMethod(final EnhancedInstance objInst, final Method
method, final Object[] allArguments,
final Class<?>[] argumentsTypes, final MethodInterceptResult result)
{
// this code cause a memory leak
AbstractSpan span =
ContextManager.createLocalSpan(generateOperationName(objInst, method));
span.setComponent(ComponentsDefine.JDK_THREADING);
final Object storedField = objInst.getSkyWalkingDynamicField();
if (storedField != null) {
final ContextSnapshot contextSnapshot = (ContextSnapshot)
storedField;
ContextManager.continued(contextSnapshot);
}
}
