The fix is titled this way:

  6969574: invokedynamic call sites deoptimize instead of executing

The bug is (a) on the mlvm patch queue, and (b) working its way through the OpenJDK RE pipeline.

Current state of (b) may be observed by looking at these three workspaces:
  http://hg.openjdk.java.net/jdk7/hotspot-comp/hotspot/shortlog  (* I push mlvm patches in here)
  http://hg.openjdk.java.net/jdk7/hotspot/hotspot/shortlog  (* hotspot team integrates here)
  http://hg.openjdk.java.net/jdk7/jdk7/hotspot/shortlog  (RE builds feed from this)

The fix 6969574 is in the starred workspaces.  Therefore, it is not yet in the binary builds from RE.
