Illegal state exception (duplicate key) while analyzing redis lettuce project

[sinha108]

Describe the bug
Analyzing the redis lettuce project at analysis level 1 results in this runtime error:

java.lang.RuntimeException: java.lang.IllegalStateException: Duplicate key connectStatefulAsync(T, DefaultEndpoint, RedisURI, Mono, Supplier) (attempted merging values Callable(filePath=./redis_lettuce/src/main/java/io/lettuce/core/cluster/RedisClusterClient.java, signature=connectStatefulAsync(T, DefaultEndpoint, RedisURI, Mono, Supplier), comments=[Comment(content=
