Timothy Farkas updated DRILL-6234: ---------------------------------- Description: Doing the following will throw an Index out of bounds exception. {code} final VarCharVector vector = new VarCharVector(field, allocator); vector.allocateNew(); vector.getMutator().setValueCount(100); {code} The expected behavior is to resize the array appropriately. If an index is uninitialized you should not call get for that index. {code} at org.apache.drill.exec.memory.BoundsChecking.checkIndex(BoundsChecking.java:80) at org.apache.drill.exec.memory.BoundsChecking.lengthCheck(BoundsChecking.java:86) at io.netty.buffer.DrillBuf.chk(DrillBuf.java:114) at io.netty.buffer.DrillBuf.getInt(DrillBuf.java:484) at org.apache.drill.exec.vector.UInt4Vector$Accessor.get(UInt4Vector.java:432) at org.apache.drill.exec.vector.VarCharVector$Mutator.setValueCount(VarCharVector.java:729) at org.apache.drill.exec.vector.VarCharVectorTest.testExpandingNonEmptyVectorSetValueCount(VarCharVectorTest.java:97) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.lang.reflect.Method.invoke(Method.java:606) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) {code} was: Doing the following will throw an Index out of bounds exception. {code} final VarCharVector vector = new VarCharVector(field, allocator); vector.allocateNew(); vector.getMutator().setValueCount(100); {code} The expected behavior is to resize the array appropriately.
