Just wanted to mention that this app worked fine on same WLS cluster before upgrading to Seam 2 CR1. It was using seam 1.2.1 GA earlier. I am not sure this is a WLS issue or seam issue. I am also working with BEA support on this. However, it will be great if someone can give insight on what is happening with seam that is causing this error.
