Summary: Error-prone X#searchForCause() implementation Key: IGNITE-16889 URL: https://issues.apache.org/jira/browse/IGNITE-16889 Project: Ignite Issue Type: Bug Components: general Affects Versions: 2.12 Reporter: Alexey Kukushkin The {{X#seachForCause}} utility method fails with a {{NullPointerException}} if the analyzed {{Throwable}} has no {{suppressed}} exception due to the [missing null check|https://github.com/apache/ignite/blob/2.12.0/modules/core/src/main/java/org/apache/ignite/internal/util/typedef/X.java#L570]. I never encountered any issues with that with real usage of Ignite. However, writing a unit test that stabs the {{IgniteCache}} methods to throw an exception without initialized {{suppressed}} exceptions results in the stabbed method to return {{null}} instead of throwing an exception. The workaround is to properly initialize the {{suppressed}} list in the mocked exception. I suggest to make the generic {{X#seachForCause}} utility method handle the case when the {{suppressed}} list is not initialized. That would simplify the unit tests code. -- This message was sent by Atlassian Jira (v8.20.7#820007)
