<i18n dev> Fwd: Re: Code review request: 7163483 JarSigner -verify -verbose does not format date string according to locale

[Jonathan Lu]

Hello i18n-dev,

Here's a question about output multiple lines in console under different 
locales, I firstly raised it in security-dev list, and proposed a patch
http://mail.openjdk.java.net/pipermail/security-dev/2012-April/004760.html
http://cr.openjdk.java.net/~luchsh/7163483/

but found no good solution for the problem of how to format the many 
fields of time string to be aligned in a column so far, so I'm 
forwarding the mail to i18n-dev, hope to get some suggestions since it 
is related to string format in different locales.

Weijun has  posted the question to core-libs-dev list, but no response yet.
http://mail.openjdk.java.net/pipermail/core-libs-dev/2012-April/010033.html

Could anybody please help to take a look?

Thanks
- Jonathan

Hi Jonathan

Some comments:

1. Can you be sure that the new format always has the same length?
jarsigner tries to output in a tabular style and each column should be
aligned.

2. You might need to reformat the modified line to make it fit into 80
characters width.

3. Why not include the test inside the changeset?

Thanks
Max
