In WicketServlet.java line 221 we have a "finally" block with
response.close() in it. Consider what happens if the "try" block throws
an exception, the "finally" block is executed and response.close()
throws its own exception: the original exception is lost. (I am guessing
that is what is going on in my case)
Can you guys rewrite this block so it throws the first exception
encountered and quietly swallows any new ones?
