Some hssfr4 spreadsheet programs crashing on ss_open().

Our rpg spreadsdheet programs that use ss_ope4n() started crashing recently.
We have not changed anything/settings on our system, nor put on
any ptfs lately.

A 3rd party vendor has, however, upgraded zend server and possibly apache on our
iseries. It's worth mentioning that the 3rd party software also uses POI to
populate spreadsheets. Also, we really do not know what all they did on our iseries.

I've stepped thru the affected programs but that sheds no light on why they are crashing.
'Unable to open workbook!'

Only programs that open a workbook are affected, the programs that create new spreadsheets
are still running just fine.

The java error message i've pasted below.

Any help, tips or direction would be very much appreciated??

Thanks,

John
