I'm trying to download the precompiled JDK to use as bootstrap, but the server is not responsive. 

For example: http://openjdkpower.osuosl.org/OpenJDK/download/bootstrap/openjdk_8u40_b13-aix-ppc64.tar.bz2 

I filed tickets last week with OpenJDK project and OSUOSL, but they seem to have disappeared into the void.
