P2 - Nullpointer Exception at RepositoryTransport.download [message #554809]

We are following the Product based build for our RCP application. Our build process creates a local P2 repository in the build directory. Once the build is successful, we copy the P2 repository to a remote URL (http).
The P2.inf (inside product plug-in) points to the remote URL. Now when I start the application, I'm getting NullPointer Exception at RepositoryTransport.download(RepositoryTransport.java:75). If I connect to the local repository (in build directory), it works fine.

I have created the following bug - https://bugs.eclipse.org/bugs/show_bug.cgi?id=323149

Please let me know if anyone has a solution for this problem?
