Please review: 7127906: (launcher) convert the launcher regression tests to java

[Kumar Srinivasan]

Hi Joe, Naoto, Sherman,

Here are the highlights of these changes:

1. The TestHelper.java is now extensible, this simplifies the usage of 
static variables
      and methods, added a couple of convenience methods and some minor 
refactoring.

2. Eliminated some shell tests,  (few more remaining, saved for a future 
project).
     a. UnicodeTest.sh, UnicodeCleanup.java merged into UnicodeTest.java
     b. i18nTest.sh, deleteI18n.sh, CreatePlatformFile.java merged into 
I18NTest.java
     c. ChangeDataModel.sh converted to ChangeDataModel.java
     d. unresolvedExceptions.sh converted and merged into 
UnresolvedExceptions.java

3.  Arrrghs.java when testing on Solaris with ja_JP.UTF-8 locale, some 
of the tests fail
      as the launcher messages in java are localized,  therefore these 
tests are skipped,
      under such conditions.

Tests: Windows English/Japanese, Solaris  C/ja_JP.UTF-8 + usual jprt 
systems (undergoing).
