Research direction
First, replicate the issue with JDK 1.8.0 20 by setting up a simple Spring Cloud Alibaba project using sentinel datasource nacos. Investigate the configuration binding in the sentinel module, specifically how 'spring.cloud.sentinel.datasource.ds.nacos.rule type' is mapped to RuleType. Check if the issue is related to Spring Boot's relaxed binding or Java reflection differences in that JDK version. Review the issue comments for any additional context or attempted fixes.
