[Bug swing/26918] New: GapContent - assertion triggered

[thebohemian at gmx dot net]

Create a JTextArea (uses a PlainDocument with GapContent inside) and type

abcd
ffff
ffff
ffff

Now move behind the d and press enter. This will trigger the following
exception:
java.lang.AssertionError: mark: 10, gapStart: 5, gapEnd: 14
