> Key: IGNITE-16889
> URL: https://issues.apache.org/jira/browse/IGNITE-16889
> Project: Ignite
> Issue Type: Bug

> 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.
