Description

The TestRouteText class includes a testPatternCache method that exhibits intermittent failures when checking the expected maximum cache size.

TestRouteText.testPatternCache:788 Expected 1024 elements in the cache for the patterns, got1025 expected:<1024> but was:<1025>

Recent changes to refactor usage of Google Guava included changing the cache implementation to use Caffeine. The Caffeine Guava migration documentation indicates that Caffeine uses a slightly different approach to eviction, waiting until the size exceeds the threshold. The test should be adjusted to avoid intermittent failures.
