And which is unfortunate since there is no lingua franca in builds.
Also, I wandered around openjdk.java.net looking for instructions to
build HotSpot separately, but found none. Any hints?

Ok, I see, thanks. "jstack -F" fails on all combinations, including
jdk7u12-ea vs. jdk7u12-ea with:

Attaching to process ID 20721, please wait...
