Thank you for the reply. Yes tomcat bundle has dynamic imports defined in it. (was added it intentionally). I was wondering why there are more than one entry for same import. I'm currently trying to keep the tomcat's dynamic import as it is and trying to find a way to resolve the multiple imports (I hope that would reduce the slowdown)
Appreciate all your help Thanks .
