Description Danny Mui 2003-03-11 19:26:09 UTC 
The following exception is generated when trying to read a file that zero bytes:

========================================
java.io.IOException: Unable to read entire header; -1 bytes read; expected
512 bytes
	at
org.apache.poi.poifs.storage.HeaderBlockReader.<init>(HeaderBlockReader.java:114)
	at
org.apache.poi.poifs.filesystem.POIFSFileSystem.<init>(POIFSFileSystem.java
========================================

Provide a more descriptive exception message.

Modified to print 0 instead of -1. Makes a bit more sense, hopefully that is
sufficient, if not reopen with a comment as to desired error text.

java.io.IOException: Unable to read entire header; 0 bytes read; expected
