Bug ID: 62165
Summary: OldExcelExtractor closed NPOIFSFileSystem too early
Product: POI

OldExcelExtractor patch file to fix the open stream bug
open(InputStream biffStream) closed the NPOIFSFileSystem right after open
which is wrong. We should only close it when open failed.
The buggy code:
try {
open(poifs);
} finally {
poifs.close();
}
Should be:
try {
open(poifs);
toClose = poifs; // Fixed by GR, we should not close it here
} finally {
if (toClose == null) {
poifs.close();
}
}
Attached is the patch file
