Additional Testing In process: ( suggested by Dan):

src/share/vm/runtime/arguments.cpp
    - test with shared archive creation and use; see the e-mail
      from Coleen

src/share/tools/ProjectCreator/ProjectCreator.java
    - just a usage message; visual inspection of the code

src/os/windows/vm/os_windows.cpp
    - comments only; no testing needed

src/os/{bsd,linux,solaris}/vm/os_{bsd,linux,solaris}.cpp
    - the only code changes come into play when the "gamma"
      launcher is used
    - and when JAVA_HOME refers to a valid JDK, the function
      fakes up a JVM path so that callers using the JVM path
      to find other things in the JDK will work.
    - I can't find any way that the actual JVM path value
      that is returned is exposed
    - I don't see a way to test this other than have a debug
      printf() or manual code inspection.
