Some tests in langtools/test/com/sun/javadoc do not use JavadocTester that maybe should.

The following script identifies candidate files that should be examined:

for f in $(find test/com/sun/javadoc -name \*.java | xargs -n 1 grep --files-with-matches @test) ; do if grep -q 'extends JavadocTester' $f ; then true ; else echo $f ; fi ; done
