Exception only occurs for certain files in a ZIP file.
I found this out while decompressing the latest Java Tutorial (ZIP version). 
While decompressing it, 4 files throws exception:

	ui/drawing/images/MovingImage.gif
	images/HJLogo/T12.gif
	java/threads/example/RaceTest.class
	java/threads/example/BidirectionalBubbleSortAlgorithm.class

Even though the exception is thrown, I found out that the 4 files are OK. There 
seem to be no corruption at all since I compared this with the files that was
decompressed using the "unzip" program from /usr/dist. 
One of the file "MovingImage.gif" is compress in ZIP format in the attachment
"a.zip".

To reproduce this bug, get "a.zip" from attachment, compile the code below and
type "java unzip a.zip".

Error message for this bug is:

Source code is:

This problem occurs 100% repeatably on two zip files that
I have, but some other files work okay.  I will send problem zip
files at your request.  The files were created by ZipIt on
the Mac, and can be deflated okay by unzip (PD version) on Win95
and by WinZip on Win95.

The output, including the stack trace, is:

+++ zip = java.util.zip.ZipFile@1cc748
+++ zip file entry 1 = ICONS/grain22.ico
+++      7358 characters
+++ zip file entry 2 = ICONS/grain12.ico
+++      7358 characters
+++ zip file entry 3 = ICONS/grain02.ico

Here is the source program, which simply accesses every byte of
every entry in a zip file:

--------- JZip.java ---------------------------
import java.util.zip.*;
import java.util.*;
import java.io.*;

class JZip {

    public static void main(String[] args) {
	try {
	    ZipFile zip = new ZipFile(args[0]);
	    System.out.println("+++ zip = " + zip);
	    Enumeration entries = zip.entries();
	    int n = 0;
	    while (entries.hasMoreElements()) {
		ZipEntry entry = (ZipEntry)entries.nextElement();
		++n;
		System.out.println("+++ zip file entry " + n + " = " + entry);
		InputStream input = zip.getInputStream(entry);
		int c;
		int count = 0;
		while ((c = input.read()) >= 0)
		    ++count;  // System.out.print((char)c);
		System.out.println("+++      " + count + " characters");
	    }
	} catch (Exception e) {
	    e.printStackTrace();
	}
    }

}
