Summary:  ZipFile.readEntries' bad perfomace for archives with many files

Original Submission:  readEntries method of ZipFile.java uses 
RandomAccessFile.java to read files byte by byte that in turn causes huge 
number of single byte read syscalls.  Thus the perfomance of this code is bad 
for archives with large number of files.
