Bug 10307

Hi...

I always got "Invalid class file format:" error during compilation
I didn't get any error message when "jakarta-poi-1.5.1-final-bin.tar.gz" 
downloaded from its site. has no problem with unzipped (#gzip -d filename).
To open the archive I used 
#tar xvfi jakarta-poi-1.5.1-final-bin.tar.gz
since always encounter checksum error I use "xvfi".

Therefore I rename the file to make my CLASSPATH simpler...
then I compile... and got the error... as shown below...


I tried to build my own poi*.jar, but seemed too complicated to me
as I know it needs another product "ant" ???

hope it clear enough...

Thanks in advance...

Detail as follow:
