[arch-general] libhpi.so in openjdk6 not in 7 or in jre/jdk 7?

All, In building several packages, I ran across a configure error that libhpi.so was not found. Checking, I find the file on openjdk6, but not in 7 and no longer in jre/jdk 7.4 from AUR. Does anybody know if this so has been renamed/removed? How to handle the builds? Just use openjdk6 or is there a standard work-around that will allow building on jre/jdk 7 or openjdk7. I've googled, but I can find a useful link. If you have one, that's all I need. Thanks. -- David C. Rankin, J.D.,P.E.
