Created attachment 177542 [details] stacks when eclipse hangs I just started to play with the b3 editor and when I added a new contribution item to indigo.b3aggr eclipse hangs. Statusline displays a truncated: "Loading p2:http://dow...tes/milestones" The UI was blocked. I'm attaching a stack trace of the hanging process. (well, actually two stack traces as I sent kill 3 twice to see if there's any observable progress). Update: after several minutes eclipse came back from the dead and the error log was full of messages (to be attached next).
Here are some of the errors from the log: org.eclipse.equinox.p2.core.ProvisionException: Artifact not found: http://download.eclipse.org/modeling/emf/updates/milestones/features/org.eclipse.emf.validation_1.2.0.v200805130238-35-9oA55S5L8G6FCT.jar. org.eclipse.equinox.p2.core.ProvisionException: Artifact not found: http://download.eclipse.org/modeling/emf/updates/milestones/features/org.eclipse.emf.validation.sdk_1.2.1.v200807161729-579093L7YxTRK7HtUz0Hhaz-JlG9.jar. org.eclipse.equinox.p2.core.ProvisionException: Artifact not found: http://download.eclipse.org/modeling/gmp/updates/milestones/features/org.eclipse.gmf.runtime.thirdparty.source_1.1.0.v20100421-2359-7F8G1FC7sRTMV4Yz-edsl.jar. org.eclipse.equinox.p2.core.ProvisionException: Artifact not found: http://download.eclipse.org/modeling/gmp/updates/milestones/features/org.eclipse.gmf.sdk.experimental_1.1.1.v20100421-2359-7A77EpEdvPqvY4viNqoRn6hjUawb.jar. ...

Unfortunately I am unable to reproduce any of the problems that you describe. According to the stack trace you attached, it looks like you clicked in the IU name property selection under a repository that was being loaded. I don't understand how you could do that since while a repository is being loaded, the IU selection should be in a disabled state (there seems to be no way to invoke the drop-down at that moment). If you are able to describe exact steps that you take to reproduce the problem it will help me a lot. Regarding the missing artifacts, it is not an aggregator bug but the repositories were probably broken when you were trying to fetch them.
(In reply to comment #2) I can't reproduce either and it seems the stacktraces already told you more than I can tell you :) It seems I had the golden click that hits the button at an impossible point in time. > Regarding the missing artifacts, it is not an aggregator bug but the > repositories were probably broken when you were trying to fetch them. I agree, but perhaps the bug only occurs in a state where some required repositories can not be accessed? Just guessing what might be the difference between my golden click and our failing attempts to reproduce.
I never again experienced this so feel free to close as WORKSFORME.
