Hi all.
We're on POI 3.1, and are getting the following exception when getting
the text pieces for some Word documents:
java.lang.StringIndexOutOfBoundsException: String index out of range: -22528
at
java.lang.AbstractStringBuilder.substring(AbstractStringBuilder.java:881)
at java.lang.StringBuffer.substring(StringBuffer.java:416)
at org.apache.poi.hwpf.usermodel.Range.text(Range.java:270)
at
org.apache.poi.hwpf.model.PicturesTable.getAllPictures(PicturesTable.java:196)
This appears to be coming from here:
public String text()
{
initText();
StringBuffer sb = new StringBuffer();
for (int x = _textStart; x < _textEnd; x++)
{
TextPiece piece = (TextPiece)_text.get(x);
int start = _start > piece.getStart() ? _start - piece.getStart() : 0;
int end = _end <= piece.getEnd() ? _end - piece.getStart() :
piece.getEnd() - piece.getStart();
if(piece.usesUnicode()) // convert the byte pointers to char pointers
{
start/=2;
end/=2;
}
sb.append(piece.getStringBuffer().substring(start, end));
}
return sb.toString();
}
A breakpoint at the call to substring shows the following values:
_start = 7468
_end = 7680
piece.getStart() = 52736
_end - piece.getStart() = -45056
I notice that trunk is significantly different in this area... so I'm
wondering how safe it would be to pull just the changes in this area
into 3.1, or whether it is a practical impossibility due to being part
of a much larger changeset.
We can't upgrade to 3.2 as updating caused about half a dozen of our own
unit tests to fail.
