I'm trying to create the sample report that comes with BIRT Runtime but I keep running into the following error:

I have the same error and couldn't determine where it's coming from.

I downloaded an archived version (4.2.2) of BIRT Runtime and ran the genReport with no issues at all. It seems that there is a problem with their current release
