java.lang.NullPointerException

Spring JIRA | Jennifer Hickey | 4 years ago
  1. 0

    The following tests in JedisConnectionPiplineIntegrationTests seem to cause various ClassCastExceptions on closePipeline(): testGetConfig() - ArrayList cannot be cast to byte[] testSortStore() - Long cannot be cast to List (while processing return of sort method, which is a Long) testWatch()/testUnwatch()/testMultiExec() - byte[] cannot be cast to java.util.List Lines up with the String QUEUED and the index of the multi operation, though that shouldn't come back from multi, so something may be off with indexing. Number of results seems accurate For example: {code} java.lang.ClassCastException: java.util.ArrayList cannot be cast to [B at redis.clients.jedis.BuilderFactory$5.build(BuilderFactory.java:49) at redis.clients.jedis.BuilderFactory$5.build(BuilderFactory.java:47) at redis.clients.jedis.Response.get(Response.java:31) at redis.clients.jedis.Pipeline.syncAndReturnAll(Pipeline.java:89) at org.springframework.data.redis.connection.jedis.JedisConnection.closePipeline(JedisConnection.java:260) at org.springframework.data.redis.connection.DefaultStringRedisConnection.closePipeline(DefaultStringRedisConnection.java:1150) at org.springframework.data.redis.connection.AbstractConnectionPipelineIntegrationTests.testGetConfig(AbstractConnectionPipelineIntegrationTests.java:131) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:74) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:83) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:72) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) {code} testMultiDiscard() -
