Now this shows up at random and when I start it up in Debug modes I dont get the error. As far as i can tell its a Equinox bug and not a Rap (the target I am using) eny ideas what could couse this would be nice.

hm. I've lost a machine.. literally _lost_. it responds to ping, it works completely, I just can't figure out where in my apartment it is.

The work around for this bug was in the end setting the start up level of the service manual to 1. This solved the whole problem. Al touch I find it strange that you have to set your Service to level 1 bc its OSGi related..

This looks to be another variation of https://bugs.eclipse.org/bugs/show_bug.cgi?id=316780

If you have a testcase available could you attach it to that bug? Thanks.

Tom.

I'm afraid I do not have a test case available. The only thing I can say is that the Circularity error is coursed because the OSGi Jetty service starts up and the entry points builds a View were it directly needs the Danamic Service and then the DS server still binding it to the tracker wants 2 instances of the same Class or somting in that line of toucht.
