Hi, I have a parsing error when trying to read an excel file

Environment : jdk 1.4.2 under Windows XP SP1, error identical under poi
2.0, 2.5.1 and 3.0-alpha2-20060616, parsing an a file created with excel
2002 (containing some french characters) :

HSSFWorkbook hssfWorkbook = new HSSFWorkbook(new POIFSFileSystem(new
BufferedInputStream(new FileInputStream("MyFile.xls"))));

Code worked a few days ago but failed since some changes in the excel file

Error is at
java.lang.StringIndexOutOfBoundsException: String index out of range: 14172
at java.lang.String.checkBounds(String.java:287)
at java.lang.String.<init>(String.java:319)
at org.apache.poi.util.StringUtil.getFromCompressedUnicode(StringUtil.java:163)

original cause is in StringUtil : "return new String(string, offset, len, "ISO-
8859-1");" where string.length - offset > len

As in all other cases len = string.length - offest  I tried to force the len 
value but it gives me a

	at 
org.apache.poi.hssf.record.RecordFactory.createRecords(RecordFactory.java:185)
so I'm stucked for now
