Subject: annoying bug in Windows XP

Hi to all readers,

this day I found a annoying misbehavior in Windows XP professional
with SP2. 

I had a directory with some Java sources (*.java) and some backup
files (*.jav). Because I din't longer need the backup files I would
delete them with 'del *.jav'. But this command also delete all the
source files. #?%*. The last backup was 4 hours ago. :-/

So I tried what happen and the result is the command above checks
only the first three chars from the extension (DOS is alive).

Here is how you can reproduce it:

mkdir testbug
cd testbug
rem.>file1.jav
rem.>file2.java
rem.>file3.javas
del *.jav

All three files are deleted. Is this a known bug or a unknown feature?
