RFR 8004547: Extend JavaFX launcher support...

[Kumar Srinivasan]

David,

It is looking good, a couple of comments and requests:
1. LauncherHelper.java: Can you please document the table below in
     LauncherHelper.java, and a note to refer to LauncherHelper.java in
     FXLauncherTest.java this will make it easier to understand everything
     in the future.

2. FXLauncherTest.java

a. testExtraneousJars, you have changed the cmd from javac to java
     using a java class, thus this error message is not accurate:

throw new Exception("jfxrt.jar is being loaded by javac!!!");

b. The case of -jar with no JAC is being commented out ? I take it this
     is redundant now ? Does this need to present ? or a todo for later ?
    If so please comment it appropriately.
    // Todo: blah
    // testBasic......

    or

    /*
     * Redundant but can be used iff .....
     * .......
     */

>> Correct. I have actually changed it to fix this case, and IMHO it cleans up the launcher code a bit.. I'll post the webrev when I'm done syncing with TL.
