I was able to track down this bug even for an 'empty' workbook (that is, nothing
is visible there). The error occurs if in a call to static method

SubRecord.createSubRecord(
  short subRecordSid, short size, byte[] data, int offset 
)

the 'size' parameters exceeds the available space in the 'data' buffer. As a
consequence.

I implemented a workaround that works for me by doing some checks in method
ObjRecord::fillFields() before the thread of control proceeds to
SubRecord.createSubRecords() there. I'm well aware this patch might be
dangerous. Find the diff of file ObjRecord.java below, the entire new file is
placed into a separate attachment (that still contains some useful trace messages).

<  Record subRecord = SubRecord.createSubRecord(subRecordSid, subRecordSize,
data, pos + 4);
---
>  Record subRecord = null;
>  if (size - (pos+4) < subRecordSize)
>  {
>subRecord = SubRecord.createSubRecord(subRecordSid,size-(pos+4)), data, pos+4);
>  }
>  else
>  {
>subRecord = SubRecord.createSubRecord(subRecordSid, subRecordSize, data,
pos+4);
>  }
