Initially when this error is occuring i don't have any report in my reports
directory. I generated two reports and now it is showing me proper report
without this exception.
I must say DSpace developer must release their build after through testing
otherwise such incidents create embarrassments for people like us.
I thank you for your support.

Hi mErRYo,
can you verify whether any reports are present in your reports directory?
by default this is/reports/ in your dspace install dir
https://github.com/DSpace/DSpace/blob/master/dspace/config/dspace.cfg#L1439
Just a wild theory at this point but if the directory is empty, it could be
that this line already sends you to a no-report
pagehttps://github.com/DSpace/DSpace/blob/master/dspace-jspui/src/main/java/org/dspace/app/webui/servlet/StatisticsServlet.java#L168
while the code still gets down to another forward on line
260https://github.com/DSpace/DSpace/blob/master/dspace-jspui/src/main/java/org/dspace/app/webui/servlet/StatisticsServlet.java#L260
At this second forward, he can't forward you anymore because you have already
been forwarded, hence the error.Can't explain it otherwise because I only see
two forwards in that servlet.
this bug could be fixed by adding a return statement on line 169.
