Then both the batchcollector and the processingnode may call close on the buffer. The second clause will trigger an assertionerror: java.lang.AssertionError: Assertion failed. at org.teiid.core.util.Assertion.failed(Assertion.java:73) at org.teiid.core.util.Assertion.assertTrue(Assertion.java:68) at org.teiid.core.util.Assertion.assertTrue(Assertion.java:60) at org.teiid.common.buffer.TupleBuffer.saveBatch(TupleBuffer.java:177) at org.teiid.common.buffer.TupleBuffer.close(TupleBuffer.java:192) at org.teiid.query.processor.BatchCollector.collectTuples(BatchCollector.java:153) at org.teiid.dqp.internal.process.RequestWorkItem.processMore(RequestWorkItem.java:352) at org.teiid.dqp.internal.process.RequestWorkItem.process(RequestWorkItem.java:278) at org.teiid.dqp.internal.process.AbstractWorkItem.run(AbstractWorkItem.java:49) at org.teiid.dqp.internal.process.RequestWorkItem.run(RequestWorkItem.java:207) at org.teiid.dqp.internal.process.DQPWorkContext.runInContext(DQPWorkContext.java:194) at org.teiid.dqp.internal.process.ThreadReuseExecutor$RunnableWrapper.run(ThreadReuseExecutor.java:118) at org.teiid.dqp.internal.process.ThreadReuseExecutor$3.run(ThreadReuseExecutor.java:288) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:636)
