RCPTT Eclipse Mars Plugin NullPointerException

Question

Hi,
I can see that Eclipse Mars has RCPTT with it, as given in https://projects.eclipse.org/releases/mars .
I downloaded Mars M6 from http://download.eclipse.org/eclipse/downloads/drops4/S-4.5M6-201503200800/ and tried to install RCPTT plugin from http://download.eclipse.org/rcptt/release/1.5.5/repository/ Update site. From Installation details I can see that RCPTT 2.0 is installed.
I tried to run the application as the steps given in https://www.eclipse.org/rcptt/documentation/faq/install-as-plugin/ . But it throws an exception.
An internal error occurred during: "Launching <AppName>RCPTT".
java.lang.NullPointerException
This is the error log.

I have attached the screen shot (Method1.PNG)
I then tried the method to go to RCPTT prespective and try to create a RCPTT project and record a test. That time a new error came, which is given in screen shot (Method2.PNG)
The Application for both the above two methods are chosen by the following steps.
Run the application which need to be tested using RCPTT. Save the run configuration as a .launch file.
Go to Run Configuration > Create New Eclipse Application under Test.
Choose the .launch file in target and click Run.
This new Run Configuration will be seen in Applications tab in RCPTT perspective.
Is this method right? However there is another option in Applications tab in RCPTT perspective. There I can add a new application by right click New and select the application. Whenever I try to select the application, it says "Invalid product location". I am selecting the location of the .product file. I tried to choose other locations like .target, etc as well. The message "invalid product location" did not go. Do I have to try this method as well? I think it need to provide me something same as the above method with I have mentioned.
Please find two images attached.
Thank you

Hi all,
I have an identical problem with Papyrus project. I used Oomph setup to configure the workspace of my IDE and I installed RCPTT plugins from the Eclipse Mars update site (http://download.eclipse.org/releases/mars).
I created an Eclipse Application under test and, when I launch it, I have a NPE.
This is the content of log file :

I added in attachment the Papyrus Launcher configuration and the AUT Launcher configuration. I wanted to attach the aimed target file but this one doesn't exist in .metadata folder.
The used target platform with my IDE is a Targlet which is created by Oomph.
