switch to second program while first one is freeze

Hi,

    I have a special requirement with silk4j. Hope anyone can help me...

    I have two programs to be tested with silk4j. Let's say them Pro1, Pro2. Pro2 is a plug-in of Pro1 and can only be launched through Pro1.

    Test steps is: start Pro1, do some operations. Then a button in Pro1 is clicked and Pro2 is launched(a login dialog is shown). At the same time Pro1 is freeze(hang). Only after the Login is done on Pro2, Pro1 can be active again(Pro2 is also active).

    As I tried sith silk4j, the operations at the beginning on Pro1 worked well. But when silk4j clicked the button to launch Pro2, Pro2 was launched successfully but the silk4j stayed there for about 15 minutes without any operation. After that, silk4j could resume to operate again(on Pro2).

    I guess for the 15 minutes, silk4j thread is waiting for some resource's release or wait for some notification. But since Pro1 is freeze, nothing received until timeout.

    The questio is, does anyone know how to reduce the 15 minutes? Pro1 and Pro2 have many interactions like above. Many 15-minutes timeouts in a test is not acceptable.

     Any idea is appreciate, thanks~
