Missing rules when using expirable maps/caches from popular open source libraries

Comienza localizando las definiciones de reglas de Java y las pruebas del repositorio para las advertencias relacionadas con SnapStart. Revisa cómo los checks identifican el uso de bibliotecas y métodos, y después cubre Guava expireAfterAccess/expireAfterWrite y las variantes de expiración de ExpiringMap. La tarea estará terminada cuando los patrones relevantes de cachés con expiración produzcan una advertencia, mientras que el uso de cachés sin expiración permanezca sin cambios.

In case the expirable cache is initialized in the constructor of the Lambda class and some entries are put as well it may happen that the entries are not there anymore after the SnapStart snapshot is restored. The should be a warning of usage of time-based cached with the SnapStart is enabled.

In particular I'm thinking of the usage of 2 popular open source libraries:

• Google Guava ( artifact id guava and group id com.google.guava) and the code like this

myCache = CacheBuilder.newBuilder().expireAfterAccess(3600, TimeUnit.SECONDS) .build();
myCache.put("key", "value");

• Using artifact id expiringmap and the group id net.jodah and the code like this

expiredMap = ExpiringMap.builder().expiration(3600, TimeUnit.SECONDS).build();
expiredMap.put("key", "value");

I know that it's difficult to spot such use cases because both open source libraries offer standard and not expirable caches. But the invocation of the methods like CacheBuilder.newBuilder().expireAfterAccess/expireAfterWrite or multiple variations of methods ExpiringMap.builder().expiration* when creating the cache using these open source tools is a clear indication of the creation of expirable cache.
