我們有一個掃描,在編碼中止之下,唯獨:sonarqube 6.3錯誤可能 - 不完整的象徵 - 執行 - 達到漲停的-16000步
org.sonar.java.se.ExplodedGraphWalker$MaximumStepsReachedException: reached limit of 16000 steps for method getServiceProviders#151 in class ServiceProviderService
我們看着規則S2259和S2583,並希望保留有關空指針的通知。
這種情況發生在「常規」和調試(-X)模式,所以它不是問題1406.在我們的情況下,它似乎確實與try/catch有關。 (請參閱下面的示例方法。)它是否可能是問題1295的復活? https://jira.sonarsource.com/browse/SONARJAVA-1295如果是這樣,是否有辦法從16,000個簡單地增加堆棧,以便我們可以移動?
樣本方法:
