Reassigning to diff.

Comment 3 Ondrej Vrabec 2009-03-27 10:19:37 UTC

Reassigning to compapp for evaluation.
Please look at this issue - to acquire a content reader the diff module calls method
org.netbeans.modules.compapp.test.ui.DiffStreamSource.createReader, which I guess internally calls 
java.util.regex.Pattern.matcher() with a null parameter.
