When copying the code snippets from the site, additional text that is hidden is copied. This required cleaning up the code snippet after pasting it.

For example, browse to http://www.jboss.org/jdf/examples/ticket-monster/tutorial/Introduction/#adding-a-new-entity-using-forge and copy one of the code snippet fragments on display. Additional text like

This text seems to be inserted by the Sharethis.com widget on the page.
