Well, that seems to be the core of your problem. I guess someone will have to 
investigate and find out if it is the right fix or not.

Has it never occurred to you that it may be a difference between OpenJDK and whatever 
patches IcedTea adds? Or a difference between IcedTea and whatever Ubuntu ships 
patched on top of that as Icedtea? Or a syncing mistake on behalf of whoever did the 
syncing?

Who knows? The one who investigates. The rational way to investigate that would be
to start with the Ubuntu build, try to reproduce the issue, compare it with a plain 
IcedTea build on Ubuntu, etc. I've seen no evidence so far of any of that work having 
been done ...

I'm not blaming you for anything. You have proposed a conspiracy theory about the 8014925 
changeset, and I simply debunked it.

If you'd like to know which changes have been bulk integrated as part of 
http://mail.openjdk.java.net/pipermail/jdk7u-dev/2013-June/006780.html
you can take a look at the corresponding pushes at

I have no idea if all of those changes are in IcedTea 2.3.x, or not. 
That's something you'll have to know or find out if you don't. There 
has been a rapid fire of IcedTea releases in the last months, so that it's
hard for me to guess what ended up in which one, and which one ended up 
in which distribution with what patches on top of that.

>From the first entry at https://bugzilla.redhat.com/show_bug.cgi?id=976693 ,
it sounds like whoever pulled those changes in into IcedTea didn't pull in
8014745, which was synced into OpenJDK 7u as part of the bulk integration
above as http://mail.openjdk.java.net/pipermail/jdk7u-dev/2013-June/006798.html
clearly shows. So was 8010118, the other issue mentioned in that e-mail.

I have no idea whether that's true and if so, what else the person doing
the integration into IcedTea might have missed. Again, this is where someone 
from Icedtea needs to figure out if that's the case or not on Ubuntu, or 
on whatever other distribution you're seeing bug reports from.

The fix for the regression in 7u25 (8016814) was discussed here, as you can see from the 
links in the previous mail I sent to the list, and pushed into 7u40 a while ago:
http://mail.openjdk.java.net/pipermail/jdk7u-dev/2013-June/006914.html

Have you cloned jdk7u25-b16 from the forest, built that on Ubuntu and
determined that it has the same issue? Have you done so for IcedTea?
Have you checked that all the changes that are supposed to be synced up are 
actually synced up? Have you checked that there were no merge errors?

OK, so 7u25 in RHEL 6 is basically a snapshot of jdk7u-dev from June? Interesting.
