In the langtools repo, there are three test framework classes each called Tester.java

Although each is OK within its limited context, the advent of using (a single instance of) javadoc to document the framework classes means that we generate docs with three instances of Tester all in the unnamed package.

In this case it would probably be good to uniqify these Tester names.

test/tools/javadoc/lib/Tester.java
test/tools/javac/MethodParameters/Tester.java
test/tools/javap/output/Tester.java

Note that the first should /not/ be renamed to JavadocTester, since that already exists, unless we can merge the two. The other two could be MPTester and JavapTester or something like that.
