How to submit a bug report

 Hi

I have noticed what seems to be a bug in poi-5.2.3 reading an xlsb binary
file with the streaming api and using an xlookup function.  The code works
properly when reading the same data content file in the xlsx format.

Can I submit a bug report for this problem?  If so, how and where do I do
it?  I am able to provide a sscce with source code and data sets, but
unfortunately I do not have the skills to diagnose the problem and prepare
a patch.

Is there a FAQ for this question that I missed?

Thanks,

Tom
