Hello
I've worked with POI library and discowered that hwpf module for word documents
dosn't work for some kind of documents. I had some exceptions connectiong with
out of bound and index was less then zero.
java.lang.StringIndexOutOfBoundsException: String index out of range: -768

After a search I discovered that adreses was to long for type short witch was
used in whole hwpf package. As i've discowered word has adreses in type
unsigned short and that's why this errors occured because type was owerflowed
and as a result we had some less zero
walues. I've changed in this module functions getShort(...) and putShort(...)
to getUShort() and putUShort(...) from package and made some changes, where
nessesary according to type (from short to int). This semsed to solve this
practicular problem. Some documends whitch were couldn't parsed with elier
version were parsed now quite good. I would like to submit this improvment. I
could send some
code but it is not made on version from repository but from stable version prom
.zip. Besides it should be done more cerfoul. But as i
compiled it seems to work fine. Please respond what should I do?? Should I send
you what I've done and You make this improvment into official version or should
I get version from repository make this improvment and commited it???
