I had a problem with the jar command which appears to occur with v4a and
v5. Specifically, when I
jar cvf my.jar <list of files>
all is well and the jar file is created. However, when I attempt
jar tvf my.jar
I get an error (sorry, my Linux box is at home, so I do not have the
exact error). Anyway, the error is more-or-less about not knowing the
compressed size of my.jar and displays absolutely nothing about the
file. I can
unzip -l my.jar
to see the contents. Also, if I use v2's jar, I can see the contents of
the jar file which was jar'd with either v4a or v5.
This isn't a big issue because I can use v2 - just wondering if anyone
else has had the same problem.
