jikes: cannot computer sytem time stamp; javac: java.lang.InternalError:
jzentry == 0
i had successfully migrated from ant 1.1 to ant 1.2. then
this...
an intermittent error has become permanent. on compiling the
same project, using the same jdk (1.3), ant 1.1 succeeds
while ant 1.2 fails. i've tried various compilers and get
the following odd messages:
jikes 1.11

any clues? my system time (nt 4.0sp6) is set to the correct
current date/time, and the java files to be compiled each
have valid date/timestamps too.
mystified. :o

Sort of.
In any case it shouldn't be up to Ant to do this, checking during
installation is another issue, I agree (we might want to add a
<verifyjar> task and call this in the install target for example).

thanks stefan! i checked the returned mime-type after 3
corrupted downloads using different user agents (it's fine -
application/octet-stream).
i finally had luck with:
lynx -dump http://jakarta.apache.org/builds/ant/release/v1.2/bin/optional.jar > optional.jar &
;)

this bug was difficult (for me) to spot. i think a checksum
of sorts somewhere would be nice. as far as i can see,
jar tf does not actually test the integrity of an archive -
just lists it's table of contents.
i found the corrupt jar using "unzip -t".
why do you think testing lib files isn't a good idea -
performance? if so, maybe do it only the very first time the
user runs ant - on setup so to speak.
oh... and i think i can speak for others on this list when i
say a big thank you to you for your continued contribution
to this list - the frequency, content and levelheadedness of
your posts make me sort ant mail by author. :>

The optional.jar at jakarta.apache.org is OK, just checked on the
machine directly.

I'm not sure I understand what you mean? Do a "jar tf" on all files in
lib? Don't think this would be a good idea.
