<Swing Dev> [11] Review Request: 8198333 ProblemList should be updated for headless mode

[Sergey Bylokhov]

Hello.
Please review update of the tests for jdk11.

The goal is to make our testing as stable as possible and exclude any 
unstable tests(I have started from the tests which may be run in the 
headless mode).

Bug: https://bugs.openjdk.java.net/browse/JDK-8198333
Webrev can be found at: http://cr.openjdk.java.net/~serb/8198333/webrev.09

  - The ProblemList.txt is update, I have created a list of new bugs for 
any tests which fail at least once in a few iterations on a different 
systems.
  - "@key headful" was added to some tests which are noop in headless 
mode, they have some checks like:
     * Desktop.isDesktopSupported
     * Toolkit.getDefaultToolkit().getClass().getName().equals/
     * GraphicsEnvironment.isHeadlessInstance()
     * SystemTray.isSupported()
    ... etc. These checks are always false in headless mode.
  - "@key printer" was added to the tests which works in the headless 
mode, and tries to print something. Some of these tests are noop w/o 
printer.
  - "@run main/othervm" was added to a few tests which fails in agentvm 
mode. This mode is a default in mach5.
  - A few typos in the tests tags were fixed.
