> Start with an empty TextArea, then double click anywhere (which normally would select
the current word), there will be basically an assertion error from here:
> java.lang.IndexOutOfBoundsException: index: index (-1) < min (0)
>         at org.apache.pivot.wtk.Component.indexBoundsCheck(Component.java:2861)
>         at org.apache.pivot.wtk.TextArea.getCharacterAt(TextArea.java:904)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.selectSpan(TextAreaSkin.java:969)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.mouseClick(TextAreaSkin.java:1023)
> The underlying problem is trying to get the character at offset -1 in the document.
> It could also occur in any document in which the first line is empty, and trying to double
click there (with a slightly different stack trace):
> java.lang.IndexOutOfBoundsException: index: index (-1) < min (0)
>         at org.apache.pivot.wtk.Component.indexBoundsCheck(Component.java:2861)
>         at org.apache.pivot.wtk.TextArea.getCharacterAt(TextArea.java:904)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.selectSpan(TextAreaSkin.java:974)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.mouseClick(TextAreaSkin.java:1023)
> (This is from the "trunk" version).
