Daemon Threads

Do not be mislead by the seemingly large amount of time spent in a number of Identity Manager’s

daemon threads, such as

ReconTask.WorkerThread.run()

TaskThread.WorkerThread.run()

Most of this time is spent sleeping, while waiting for events. You must explore these traces to see

how much time is actually spent when they are processing an event.

class A

{

public A()

{

this(0);

}

public A(int i)

{

}

and:

class B

{

public static void test()

{

new A();

}

The call tree will look like this:

B.test()

-A.<init>(int)

-A.<init>()

Rather than this:

B.test()

-A.<init>()

-A.<init>(int)
