Thanks. Indeed, I found the change through the hg mirror of the old
openjdk svn repo: http://icedtea.classpath.org/hg/openjdk/
It is in revision ce9dde984c21, which corresponds to:
Summary: [svn] Load openjdk/jdk7/b22 into jdk/trunk.

So it was in b22. That should help us track down the actual change. But
not directly, since in the old svn days no individual changesets were
available. Also note that back then the jdk tree was called j2se.
