I did some googling and found the source code for org.jdesktop.jdic.init.JdicManager online. I notice that it does this in the initShareNative method.... binaryPath = (new URL(JdicManager.class.getProtectionDomain().getCodeSource().getLocation(), ".")).openConnection().getPermission().getName();
Karl and I talked about this. It appears that this code assumes it can use this hack to get the the path to the JAR file. This is clearly a hack and will not always work as is witnessed here.
The URL associated with a code source does not necessarily have to be the URL to the JAR. In the case of OSGi, the location is not spec'ed to be a URL to the JAR. Further, since the framework caches the installed bundle, there is no guarantee the URL need to point to anything or the same JAR that the framework has cached.
The above code will not work in Felix as-is since the associated protection domain has a fudged URL set by Felix.
It has little to do with that. It has to do with the code above making faulty assumptions.

I think it would be possible to make Felix create a working ProtectionDomain for most bundles (though not for the system bundle). --- On Thu, 5/28/09, Triquoit Mathieu<mathieu.triqu...@gmail.com> wrote:From: Triquoit Mathieu<mathieu.triqu...@gmail.com> Subject: java.io.IOException: FakeURLStreamHandler can not be used!
