Works, new lines can be added but no exception is thrown. However, I see the
following debugging statements when the program starts:
getKeymapName: MetalTextFieldUI
getKeymapName: MetalTextFieldUI
getKeymapName: BasicTextAreaUI
getKeymapName: BasicTextAreaUI

I removed the debug statement and close this bug now.
