"Target platform initialization failed" error when trying to launch an SWT application in [message #1840561] Mon, 19 April 2021 07:39 Go to next message

Dear all,

I'm trying to launch a SWT application under test through RCPTT IDE. I've tried 2 versions:
- 2.5.1 Release
- 2.5.2.202104182355 Nightly

When I'm using "New Application Under Test' option and I provide location of the app, I get "Target platform initialization failed" error. It seems that the application initialization fails when checking for plugins. May this be an issue?
If so, which plugin do I need in the SWT app or RCPTT plugins folder?
Thanks in advance for Your help.

Java version:
java version "16" 2021-03-16
Java(TM) SE Runtime Environment (build 16+36-2231)
Java HotSpot(TM) 64-Bit Server VM (build 16+36-2231, mixed mode, sharing)

Best regards,
Krzysztof

I have found that one cause of this symptom is when my aut definition is based on an Eclipse launch configuration. Occasionally my launch configuration ends up with some of the start levels missing (this is an OSGI application). If you have this error and check your Eclipse log you will see RCPTT has thrown a NumberFormatException. I have not been able to determine what triggers the saving of a launch configuration with the start level missing. I work around the issue by opening the launch configuration with a text editor and searching for "@:true". Then I add the start level back to the strings found.
