Please review 7156976: improve java tools testing

[Kumar Srinivasan]

Hi,

We are adding new test to test the tool functionality of the launcher:

1. verify the options intended for a tool does gets to it intact, Steve 
Sides
     from SQE has contributed this test, which applies various test 
vectors to
     a simulated javac launcher.

2. enhanced the version checking to ensure a tool can be launched

3. The version checker now has inverted logic to select the tool selection,
      it will execute all possible tools in the bin directory. Thus any 
new tools
      added will be tested. Therefore, if a new tool is not compliant, 
the onus is on
      the tool developer to:
           a: make the tool compliant.
           b: if a is impossible,  then add it to the excluded list.
