Sarvesh Tamba commented on KAFKA-7743:
--------------------------------------
The following unit tests throw exceptions consistently(but it's execution
status is PASSED) on SLES12-SP2 for kafka 2.1:-
org.apache.kafka.streams.state.internals.WindowStoreBuilderTest >
*shouldThrowNullPointerIfValueSerdeIsNull* *PASSED*
pure virtual method called
terminate called without an active exception
org.apache.kafka.streams.state.internals.RocksDBStoreTest >
*shouldRespectBulkloadOptionsDuringInit* *PASSED*
pure virtual method called
terminate called without an active exception
> "pure virtual method called" error message thrown for unit tests which PASS

> Key: KAFKA-7743
> URL: https://issues.apache.org/jira/browse/KAFKA-7743
> Project: Kafka
> Issue Type: Bug
> Components: streams, unit tests
> Affects Versions: 2.0.0, 2.0.1, 2.1.0
> Reporter: Sarvesh Tamba
> Priority: Critical
>
> Observing the following messages intermittently for a few random unit tests,
> though the status for each of them is PASSED:-
> *"pure virtual method called*
> *terminate called without an active exception"*
> Some of the unit tests throwing above messages are, besides others:-
> org.apache.kafka.streams.kstream.internals.KTableImplTest >
> shouldThrowNullPointerOnTransformValuesWithKeyWhenMaterializedIsNull PASSED
> org.apache.kafka.streams.processor.internals.GlobalStreamThreadTest >
> shouldThrowStreamsExceptionOnStartupIfThereIsAStreamsException PASSED
> org.apache.kafka.streams.state.internals.CachingSessionStoreTest >
> shouldNotForwardChangedValuesDuringFlushWhenSendOldValuesDisabled PASSED
> org.apache.kafka.streams.processor.internals.StoreChangelogReaderTest >
> shouldCompleteImmediatelyWhenEndOffsetIs0 PASSED
> org.apache.kafka.streams.kstream.internals.KStreamKStreamJoinTest > testJoin
> PASSED
> org.apache.kafka.streams.kstream.internals.KTableFilterTest >
> testTypeVariance PASSED
> org.apache.kafka.streams.kstream.internals.KTableKTableInnerJoinTest >
> testNotSendingOldValues PASSED
> org.apache.kafka.streams.processor.internals.GlobalStreamThreadTest >
> shouldThrowStreamsExceptionOnStartupIfThereIsAStreamsException PASSED
> org.apache.kafka.streams.processor.DefaultPartitionGrouperTest >
> shouldComputeGroupingForTwoGroups PASSED
> org.apache.kafka.streams.state.internals.RocksDBWindowStoreTest >
> shouldFetchAndIterateOverExactKeys PASSED
> org.apache.kafka.streams.state.internals.FilteredCacheIteratorTest >
> shouldFilterEntriesNotMatchingHasNextCondition PASSED
> org.apache.kafka.streams.state.internals.GlobalStateStoreProviderTest >
> shouldThrowExceptionIfStoreIsntOpen PASSED
> This probably causes the 'gradle unitTest' command to fail during cleanup
> time with final status as FAILED and the following message:-
> "Process 'Gradle Test Executor 16' finished with non-zero exit value 134"
> This intermittent/random error is not seen when final unit test suite status
> is "BUILD SUCCESSFUL".
> Reproducing "pure virtual method" issue is extremely hard, since it happens
> intermittently and for any random unit test(not the same unit test will fail
> next time). The ones noted above were some of the failing unit tests
> observed. Note that the status next to the test shows PASSED(is this correct
> or misleading?).
