Why there is only one thread can actually started in @PostConstruct method?


Why there is only one thread can actually started in @PostConstruct method?

Hope this helps Because you're not creating threads. Instead of that you're creating Runnable instances and then running their run method.
Instead do this:
code :
new Thread(threadAlpha).start();
new Thread(threadBeta).start();

seems to work fine As well explained in this link,
Will disposing an object that has a thread started on its method remove the need to call Thread.Abort()

fixed the issue. Will look into that further Consider the following code using the .Net 2003 Framework. , Your code:
code :
Public Sub startThread()
    Dim t As New System.Threading.Thread(AddressOf someObject.someSub)
    t.Start()
End Sub
Public Sub Dispose() Implements IDisposable.Dispose
    someObject.Dispose()
End Sub
t = New System.Threading.Thread(AddressOf Me.someSub) 
t.Start()

Hope this helps There won’t be a visibility problem. The Java Memory Model guarantees that everything done (or visible due to a happens-before relationship) in one thread before a call to Thread.start will be seen by the thread that was started:
From the specification in the JLS section 17.4.5:
C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thread A)

C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thread A)

I wish did fix the issue. Typically, this is unnecessary. You can call a method on any object from any thread, and this is a good thing... UI components and some legacy COM components tend to be the only items which must be accessed from a specific thread.
Instead of trying to call a method on a different thread, normally, you'll try to use synchronization (ie: lock(...) and similar) to protect access to the data itself, and make it safe to work with from multiple threads.

I wish did fix the issue. This happens because you are overriding @PostConstruct method.
