Questions about exception error with gnu.testlet.java.io.PrintWriter.jdk11 & gnu.testlet.java.io.FilterWriter.write

["Patrick Ellis" <Patrick dot Ellis at sas dot com>]

I get the following exceptions when trying to compile gnu.testlet.java.io.PrintWriter.jdk11 & gnu.testlet.java.io.FilterWriter.write.
Is there anything in the code missing or is the URLpackage  missing?
