Re: [p2-dev] Problems with boostrap installs, mysterious missing jars, and checkCertificates errors.

Since you seem to think that the missing file should have been downloaded, the first thing is to see why it has not been and why it has not failed. To see what is going on try putting a breakpoint in:
	DownloadManager#start(...) - This is the method that is responsible for downloading all the necessary artifacts.
	SimpleArtifactRepository#downloadArtifact( ) - This method is where the actual download is happening.

Subject: [p2-dev] Problems with boostrap installs, mysterious missing jars, and checkCertificates errors.

p2,

Our product upgrade process consists of using the p2 director to tear down an existing install and then install the new version of our root IU.

Recently I've started seeing the following failure during the install process:
~~~

It's true, the file's not there, but that's because it seems like p2 didn't install it and we got to running checkCertificates on a file that wasn't yet installed. We're using platform 3.8.1.

I've seen this issue before and it appears to be a race, and depending on the OS it might not reproduce.

Has anyone else seen something like this?

Any pointers on where to start digging?

Cheers,
Carlos.
