I am experiencing a problem where Rational Application Developer 8 consistently hangs indefinitely on startup. I’ve only been able to find a partial solution: I can get RAD to start up if I delete the <n>.tree file in the workspace’s .metadata.plugins\org.eclipse.core.resources.root directory. Once started however, all projects must be re-imported.
What I can’t seem to solve is the underlying issue — the issue recurs after every shutdown of RAD, and I’m having to delete the .tree file and re-import the projects each time I start the app. Shutting down RAD normally does not prevent the problem from recurring; neither does removing all projects and cycling RAD with no projects (problems start again immediately the first time RAD is shut down with projects still imported). I’ve even created a new workspace from scratch, but it didn’t help either.
I’m at a loss. If anyone has experienced this, any insight would be greatly appreciated.
I am currently experiencing the same problem with an older version of RAD and haven’t found a working solution yet so far, but you might get some pointers from here:
How do I prevent Eclipse from hanging on startup?
At any rate, you can check the ./metadata/.log file in your workspace for useful information about where exactly it hangs.
