Research direction
Start by reviewing the RSPEC-1194 link and the Java examples in the issue, then inspect existing static-analysis recipes and their tests to find the appropriate entry point. Done means the analysis flags classes extending java.lang.Error while leaving classes extending Exception compliant, with tests covering both examples.
