Cannot get JvmList in wpf (.net framework 4.7.2)

[Nik998Old]

So when I try to run the code in a WinForms-application everything works fine.
When I try to run the same code in a WPF-application, accessBridge.EnumJvms() returns 0.

This is my code:

AccessBridge Java = new AccessBridge();
Java.Initialize();
DoEvents();
var test = Java.EnumJvms();

This is my DoEvents method for wpf (should be equivalent to WinForms Application.DoEvents()):

public static void DoEvents()
{
    Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new Action(delegate {}));
}

test.Count is always 0 in wpf.
Working fine in WinForms.
