Jiang Xin commented on FLINK-33414:
-----------------------------------
[~mapohl] I think it is caused by this
[change]([https://github.com/apache/flink/pull/23244)] about junit5 migration.
In this change, the "assertThat(e,
FlinkMatchers.containsCause(NoResourceAvailableException.class));" is replaced
by ".hasRootCauseInstanceOf(NoResourceAvailableException.class)". The test
would not fail even if the root cause is a TimeoutExcption before the change,
because the NoResourceAvailableException is also is in the error stack trace.
However, after the change, the root cause has to be
NoResourceAvailableException.
> MiniClusterITCase.testHandleStreamingJobsWhenNotEnoughSlot fails due to
> unexpected TimeoutException
