We're building an application in Java based on Eclipse. Its entry point implements IApplication. In some cases, we let Eclipse restart the application by returning the exit code IApplication.EXIT_RESTART.

We try to find out how to differentiate between the appliation being started initially and being restarted. One attempt was to alter the content of system property eclipse.exitdata accordingly, but the restart always uses the original command line options, not the changed ones.

What would you suggest?

org.eclipse.equinox.launcher 1.3.100v20150511-1540

We ran into similar "requirements" with Oomph. It seems to me that there is no persistent information you can store or put anywhere, other than the file system, for this purpose. So that's the solution we used, i.e., write something (in our case to a file in the instance location, i.e., in the workspace metadata for our plugin) to record the information we needed. We save their on shutdown and can look for it on startup, cleaning it up at that point... If your application doesn't have/use an instance location, you could use the configuration location...
