{code}
In case any tests failed with TimeoutException
`org.apache.ignite.internal.testframework.junit.DumpThreadsOnTimeout` tried to
produce readable message but fail with NPE in case when Exception message is
null. After this NPE JUnit thread die and BeforeAll\BeforeEach methods are not
called. As result, we have unkilled AI3 live nodes which holded ports and next
tests on the CI Agent where it failed cannot run correctly with reason `Caused
by: java.lang.IllegalStateException: No available port in range [3344-3344]`
