Crash when rendering report

[rbrooklyn]

Hello.

We are currently using birt 4.10. When upgrading to 4.16, I am now getting crashes.

The stack is below. I'm unsure what is triggering it as it works fine with other reports tested so far. If I'm able to reliably recreate the crash I will attached a rptdesign file, for now I sadly cannot share the rptdesign file. I'm hoping the below is enough to help.

It seems to be that you use a rank()-calculation function of BIRT because the exception comes from "calculateRank()"
which tries to sort your list,
But your list hasn't any value and this case is not fetched. I changed this situation and it will be included with BIRT 4.17.
But you can take a look into your report to find the rank-function and in the meantime you can replace it with a standard SQL-rank-method.

The fix is merged to the master with PR #1798

Thank you for fixing this so quickly.
