      Description

      test_gamma script in Mac os X build is failing on 8 as shown in mail conversation below.
      To fix the problem in the 8 build means fixing it in 7u because it's a 7u libjava that is used
      with the gamma launcher. It will have to be fixed in 8 for future Java versions.

      The error doesn't affect the 7u build because the script detects a non Open JDK bootstrap is being used
      (the Apple JDK) and it exits quietly.

      Great. That's good to know. From what I can see, the reason why 7u does not show the
      same symptom is because test_gamma bails out in the 7u build because it doesn't know
      the file/directory structure of the Apple (boot) JDK. So, it doesn't actually run the test.

      Since 8 is using an openjdk 7 bootstrap, it does know where to find the files and it runs
      the test. The main Java launcher is able to deal with LANG not being set. It sets
      user.language to a reasonable default. But, it appears like gamma doesn't do that
      (and hence the null key for Hashtable.put()).
