Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
Swing interfaces should be constructed and shown from the Swing event dispatch thread. Doing so from any other thread, such as from ``++main++`` risks deadlocks since you run the risk of multiple threads accessing things which are inherently not thread-safe.
|
|
|
|
|
|
Instead, use ``++SwingUtilities.invokeLater++`` or ``++SwingUtilities.invokeAndWait++`` to kick off a ``++new Runnable++`` that handles your GUI creation.

JFrame frame = new JFrame();
