I just tried upgrading to the latest build (core 2.5.0.201906210301) and during the first boot up I had circular reference errors (pasted below) fill up my logs, repeating indefinitely .

I restarted the process, and the second time it got further, installing most packages but complained over and over about 1. java.lang.NoClassDefFoundError: Could not initialize class org.glassfish.jersey.media.sse.SseFeature which i believe is a known error?

The embedded SSH server did not start on the second restart (i have seen this before on builds of late). Its possible other bundles did not start properly as well, but thats the only one i noticed.

Restarting a third time seemed to resolve all issues and so far the system looks normal.

circular reference errors:

@digitaldan Do you maybe know if there is a specific bundle involved in your case which is not part of OHC and could be the cause for this circular reference (see #989 (comment))?

@cweitkamp Let me know if I can help test.
My test system only has the Z-Wave binding. I can try the test again without that binding if that would be helpful.

@cweitkamp apologies for missing your response in Aug, I am not aware of any bundle that would have specifically caused this, and I don't think i have seen it happen in other upgrades (nightlies) since then, but i am about to upgrade right now and will let you know if it happens.

I have quite a few bindings installed if it helps, this should be similar to what was installed in Aug.

I run into this circular dependency myself from time to time (but very rarely).

If I run into the problem the situation is mostly the same:

  • I updated my systems and start them the first time (to be clear, this occurs not on every update, but "simetimes")
  • The load if very high

Today I took a moment to analyze it a little bit as I would like to eliminate that annoying behaviour.

For me it seems that this is caused by calling "open" of the service tracker in the activation phase of the component itself. The open will try to bind the referenced services (and eventual activates it). This will result into a possible cycle.

Opening a service tracker in a component activation method is not generally wrong but in this case it could create a cycle.

What I have done to (hopefully) eliminate the problem:
I changed the activation method of the abstract registry:

  • The provider tracker is now created and opened asynchron (so in another thread).
  • In the close method I join that async task and close the provider tracker.

This way, open is not called in the component activation phase anymore and deactivation works as before.

At the moment I cannot reproduce the error while simulate the scenario (first start after update) multiple times.
