This is a code generation task. You are expected to write working code that solves the described problem.
<issue>
      After attempting to upgrade to 4.9.0, I started observing a regression throwing an ISE when analyzing some of our files.  Best guess is that this has to do with nested generics and the compilation settings of the file.

The existing stack trace is:

The signature of the method is:

`public void execute(Map<String, List<String>> parameters, PrintWriter output) throws Exception {...}`,

and it appears that the parser is complaining about the `Map<String, List<String>>` construct in the first parameter.

This file was able to be parsed in 4.8.6 without any errors being surfaced.

</issue>
Focus on implementing the required functionality correctly and efficiently. Treat this as a programming challenge.
