I agree. Now that I know what is it doing.

What jdk do you suggest here?

What makes you say I am not using the latest? I did update to 1.11.1 for
this latest build.

I'm not working on an old release, though. I am grabbing the same tarball
from the same location as the build does for icedtea. I am confused though,
as to what actual tarballs I should be grabbing.

At the moment, I am taking:

jaxp144_03.zip
jdk6-jaf-b20.zip
jdk6-jaxws2_1_6-2011_06_13.zip
openjdk-6-src-b24-14_nov_2011.tar.gz

Do I need more? From the build log, it seems this is all that is required.

Okay. This makes more sense now.

Yes, I noticed this with the change to 1.11.1, and removed those from my
Makefile.

It is the same checksum, though, and the same location that is fetched
during the icedtea build. I just pre-fetch them, and assign it as a
configure option.
Here is a link to the files with the checksums that are used:

Thanks! :)
