Error file has following conditions.
- Has named cell.
- Named cell has comment.
- Name of named cell or comment has multibyte characters.
I fixed NameCommentRecord as follows.
----
//Constructor. NameCommentRecord(final RecordInputStream ris)
if (in.readByte() == 0) {
field_6_name_text = StringUtil.readCompressedUnicode(in,
field_4_name_length);
} else {
field_6_name_text = StringUtil.readUnicodeLE(in, field_4_name_length);
}
if (in.readByte() == 0) {
field_7_comment_text = StringUtil.readCompressedUnicode(in,
field_5_comment_length);
} else {
field_7_comment_text = StringUtil.readUnicodeLE(in,
field_5_comment_length);
}
---
So I can read file.
I think the serialize method have to change too.
Please check my changes.
regards.
