For the throwing-constructor case the chain also carries the former root-cause assertions via `hasCauseInstanceOf(InvocationTargetException.class)` + `hasRootCauseInstanceOf(IllegalStateException.class)` + `hasRootCauseMessage("boom")`. All 6 tests pass locally (`mvn -pl store -am -Dtest=MessageStoreFactoryTest test`). ########## store/src/test/java/org/apache/rocketmq/store/plugin/MessageStoreFactoryTest.java: ########## @@ -0,0 +1,185 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
