Bug fixes for com.sun.imageio.plugins.png.PNGMetadata

Hi!

I've recently encountered a bunch of bugs in PNGMetadata:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5106550
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5082756
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6541476

For the first I have written a fix and posted it to jdk7-dev:
http://mail.openjdk.java.net/pipermail/jdk7-dev/2008-October/000272.html
In the meantime I found the overview of all mailman lists, and started
to wonder whether the PNGMetadata implementation belongs to jdk7 (as the
com.sun classes belong to the jdk implementation) or rather core-libs
(as ImageIO is a core library). As I still didn't get any reply there,
I'll try my luck here. Would you consider this on topic here?

I'm interested in contributing my fixes for these other issues as well.
I might even look at some more IIO metadata bugs out there, see
http://bugs.sun.com/bugdatabase/search.do?process=1&category=java&bugStatus=1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9&subcategory=imageio&type=bug&keyword=metadata

But before I start flooding this mailing list with them, I'd rather get
some replies first.

1. Is there someone going to sponsor this?

2. Do you want them all in a single hg branch or rather multiple
separate branches? I guess the issues would be independent enough to
allow bultiple independent branches.

3. I tend to have multiple commits per fix. Do you want a diff for each,
or rather a single hg bundle containing them all, or both of this?

4. Would you prefer a public hg branch somewhere to exchange the current
state of affairs?

Greetings,
 Martin von Gagern
