[Bug swing/27418] New: NPE in BasicTextUI.damageRange.

[audriusa at bluewin dot ch]

The BasicTextUI.modelToView may return null, but damageRangle does not expect
this. This causes NPE in the Protege OWL plugin during the attempt to add the
new Protege class:

java.lang.NullPointerException

The NPE can be avoided by checking for null here, but probably the null should
be never returned?
