Hi Volker,

You'll probably need to send the webrev to serviceability-dev, awt-dev 
and 2d-dev to catch more of the areas that are touched here.

I don't have time to look at this closely now but just a few comments 
from a quick pass:

1. There are a few changes for OS/400 in the patch, are they supposed to 
be there?

2. In src/solaris/native/sun/nio/ch/Net.c then I don't think the 
throwing of UOE is needed in any of the join or block functions. Instead 
you should be able to just adjust the error handling to map EOPNOTSUPP 
to IOS_UNAVAILABLE and it should work (at least I assume the issue is 
that AIX must be failing with EOPNOTSUPP rather than ENOPROTOOPT). You 
can also just return IOS_UNAVAILABLE isSourceFilterSupported return 

3. src/solaris/native/java/net/linux_close.c. Given the expanded usage 
then we should really consider renaming this. Also given the lack of 
__attribute((constructor)) support then it might make sense to always 
initialize the close mechanism from JNI_OnLoad (on platforms that need 
it). This is something for net-dev of course.

That's all I have for a quick first pass, there are actually a lot less 
changes that I expected. The patch reminds me (again) that we really 
need to sort out the src/solaris tree. I'm actually curious if it would 
build with the AIX specific sources in src/aix.
