getLastRowNum() limited to 32767 even though it returns "int" in 1.5.1

[Chris Handorf]

Create a spreadsheet with > 32767 rows in it.
Then load it and call getLastRowNum() on the sheet.  (using POI 1.5.1)
 
Even though it returns an "int" the value itself is limited to 32767
which is Short.MAX_VALUE.
 
Bummer.
