ConcurrentModificationException in progress dialog

Concurrency LayoutFramework

In the progress dialog in EPP (i.e., TL 6.6), a ConcurrentModificationException occurred during one of several attempts:

An error occurred while updating the view.
...
An error occurred during rendering of the update fragment. (java.util.ConcurrentModificationException)

java.util.ConcurrentModificationException

[...]

Assumption: Although the LogControl._messages list is populated using `synchronized`, it is iterated through in ` internalWrite ` without `synchronized`. This causes the exception. The list should always be accessed using `synchronized`.
