> {{S3LifecycleConfiguration.convertFromOzoneExpiration()}} calls {{ozoneExpiration.getDays() > 0}} (line 482). However, {{OzoneLifecycleConfiguration.OzoneLCExpiration.getDays()}} returns a nullable {{{}Integer{}}}. For lifecycle rules that specify an expiration date instead of a {{Days}} value, {{getDays()}} returns {{{}null{}}}. The subsequent comparison triggers auto-unboxing, resulting in a {{NullPointerException}} that propagates to the client as an HTTP 500 response.
> A similar issue exists in {{convertFromOzoneAbortIncompleteMultipartUpload()}} (line 500), where {{getDaysAfterInitiation()}} also returns a nullable {{Integer}} but is compared without a null check, making it susceptible to the same {{{}NullPointerException{}}}.
> There are currently no tests covering the GET lifecycle code path for rules that use date-based expiration. As a result, this bug was not detected by the existing test suite.
