Description

Tests generation failed because ClassId.canonicalName has thrown an exception

To Reproduce

1. Run Contest Estimator with method com.google.common.base.CaseFormat.* and 300s time limit.

Actual behavior

     {
        // Couldn't generate some tests. List of errors:
        // 
        // 1 occurrences of:
        // ClassId com.google.common.base.CaseFormat$1 does not have canonical name
    }
