Ant Jar Issue

[Jackie Xiao]

Sorry, adding the missing exception message:
Constructor threw exception; nested exception is java.io.IOException: DerInputStream.getLength(): lengthTag=127, too big.

Which should mean the certificate file was corrupted.

​Dear list
When jar-ing a module which contains binary certificate file (auth.p12) on CentOS, with Ant 1.9.2, it seems the p12 file was corrupted after jar compression. (When reading the cerf file with InputStream, below exception was thrown)
BUT, if we open the result jar with 7zip on Windows, drag out the p12 file, then drag into the jar again, the certificate file can be read without problem by InputStream.
So, 7zip can compress the file correctly, which made me guess it's the jar task which caused the problem.

So I use "jar xvf jarfile" to unjar, then "tar xvf myfile.jar *" to "tar a jar file", and it worked....
Have you guys encounter the same issue, or any suggestions.

Thanks in advance.

the distinction between compressing using the jar compression algorithm with ant jar task which employes LZ+HUF
http://compressionratings.com/i_jar.html

and packaging a signed jar which expects these attributes to be honored
compression algorithm
alias
storepass
signature algorithm

to create a signed jar with those attributes use signjar

At the same time 7zip has been able to extract the certificate so the
archive itself has been readable for 7zip. This indicates the archive
was correct but you've run into an issue with the code that is
extracting the jar.

I'm not sure I understand which jar you've expanded. The one created by
Ant or the one created by 7zip.

If it has been the original archive, this also means the jar tool has
been able to read the archive. This would hint the problem is within
the code you use to read the archive.
