Object invoked has disconnected from its clients

The basic idea is assumed references are absent or wrong at runtime. Since the binary workbook macro runs from Java, debugging it is already a layer removed.

The fix was to specify the workbook:

ThisWorkbook.ActiveSheet.Rows(1).Delete

Usually, I just call the subroutine and all that, everywhere. It was okay until now. Now, I have to think about this; the difficulty is compounded by not being locally reproducible. “Works on my machine!” Ha.
