[Bug swing/27837] New: ArrayIndexOutOfBoundsException in javax.swing.text.GapContent

[hendrich at informatik dot uni-hamburg dot de]

Running the attached testcase (taken out of a larger app) with classpath
cvs 2006.05.31 results in AIOOBEs. The app creates a textarea, writes a
long text into it, and then replaces the long text by a short text - without
explicitly updating the caret position. I didn't bother to remove the
invokeLater stuff (which is required in the original app with multiple threads
writing to the console).

There is already an assertion in GapContent.java, but only after the 
out-of-bounds access :-)
