This does seem to a merge issue.
When the source reorganization was pushed to jdk9/jdk9 (and immediately to jdk9/dev) then the resource was in sun/datatransfer.
Soon afterwards there was an integration + merge from jdk9/client -> jdk9/dev that brought this change:
http://hg.openjdk.java.net/jdk9/client/jdk/rev/e4724b19c64bthat moved it to sun/datatransfer/resources. Unfortunately the merged bits aren't quite right as you have found.
Has there been a bug created for this? -Alan.
