Added break statement since we are no longer using return statement.

Note: isOnWayland() - is a three way assignment (i.e `a = b = c`)
`isOnWayland = result = (display != null && !display.trim().isEmpty())`

Integer.getInteger() used here since the return value expected is of type
integer.

tryGtk - Boolean.parseBoolean(System.getProperty()) used instead of
Boolean.getBooean() since "awt.robot.gtk" has a default value of true.

Needs careful review. With the updated code I'm directly assigning toolkit
thread to new Thread as below
toolkitThread = new Thread(ThreadGroupUtils.getRootThreadGroup(), this, name,
0, false);

Boolean var `result` not required hence removed and replaced with simple return
true or false with updated code changes (as below).

Boolean.getBoolean() is used here since default value is false for
awt.robot.screenshotDebug.

Review required. In the original code IOException was being thrown here -
AccessController.doPrivileged(
new PrivilegedExceptionAction<ArrayList<String>>() {
public ArrayList<String> run() throws IOException
Now that the doPrevileged calls is removed, Do we catch the IOException and
print stacktrace or propagate it?
If the IOException is propagated then IOException needs to be thrown by method
that in-turn call execCmd().
