Two of us have created Eclipse RCP 2020-03 configurations with Java 17 on Windows following identical instructions. When running as an Eclipse application, both of us seem to get good launches the first time. However, on subsequent launches, I get the following error in the development Eclipse console, and some UI menu selections in the launched child will not show because they do not seem to be properly initialized. Any suggestions on what might be causing this and how to fix it are greatly appreciated.

java.lang.NullPointerException: Cannot enter synchronized block because "profile" is null

I added a null guard via this bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=580237

And that's available in this build:

What does self-hosting mean? I am curious why this happens to one of us and not the other. Is there a change we can make in our build to avoid this until the fix percolates to a stable release?

I would generally never expect the profile of an installation to be null because without a profile it would not be possible to install or update anything. So I assume that happens only when you launch (run/debug) an application from your IDE, which is referred to as self-hosting because the profile ID is "SelfHostingProfile" in that case...

Perhaps on the launch configuration changing the Configuration tab's "Support software installation in the launched application" to true will ensure there is a non-null profile...

That stopped the null pointer exception, but now I get

!ENTRY org.eclipse.oomph.setup.core 2 0 2022-06-22 07:22:48.275
!MESSAGE The Eclipse Git-hosted URI 'http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/interim/GMFRuntime.setup' is blocked for direct access.
Please open a Bugzilla to add it to an official Oomph catalog.
For initial testing, use the file system local version of the resource.
Alternatively, run the setup archiver application as follows:

Yes, this was failing to get into the catalog after adding it this morning.

https://ci.eclipse.org/oomph/job/setup-archiver/20118/

But it got just added by this job as I was answering you:

https://ci.eclipse.org/oomph/job/setup-archiver/20119/

There might be another 10 minute delay before the problem goes away for you (until the server serves the new setups.zip).
