I use Java 21 together with the Eclipse target platform 2024-06.
My Eclipse RCP application starts fine when launched inside the Eclipse IDE.
When I start the bundled program however, I see the splash screen for a few seconds, then the program stops unexpectedly. The last entries in the log file contain "Framework stop" and finally "Activator stopped".

I also started the .exe file from a cmd window but do not see additional information that would help me finding the problem.
Any idea what could cause the program to be stopped or how I can find the cause of the problem?
With the help of a colleague, I found the additional log file <RCP App Home>/.data/.metadata/.log.
This file contained useful information that helped me find the solution for my problem after consulting this answer.
