I noticed that putting some text to the console via TextConsole.newOutputStream().write(String) does put the text into the console correctly, but does not move the caret.

First of all, it looks weird, because the cursor is now at a position in the console where no inserting characters is possible. This alone needs to be fixed (or the caret needs to be positionable).
If the user does now input normal text into the console, e. g. by typing "test" or alike, the caret immediately jumps to the end of the uneditable region, and the typed characters are put in correctly. Still, its not intuitive, that the caret jumps around, and there is no possibility to control the caret of the IOConsole UI part.
But this also can cause exceptions: when typing a few characters in the console, and then writing some String into the console, the String is appended to the end of the previously typed text (but the caret is, as mentioned, still right before the via-OutputStream-inserted text). Now, when the user uses Backspace one or two times, an exception is thrown:

More about it: see reproduction guide.

Reproducible: Always

Steps to Reproduce:
Setup: Zero-configured IOConsole:
IOConsole ioConsole = new IOConsole("MyIOConsole", null);
ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[] {ioConsole});

1) go to the console view
2) type some text, e. g. "Test" (do not press enter)
3) insert some String to the console via one of the console's OutputStreams
4) press backspace twice (e. g. by a handler activated by a toolbar button)
