import org.apache.arrow.memory.RootAllocator
val rootAllocator = new RootAllocator(Long.MaxValue)
val v1 = new VarCharVector("var1", rootAllocator)
v1.allocateNew()
val valueCount = 3970 // use any number >= 3970 will get similar error
for (idx <- 0 until valueCount) {
v1.setNull(idx)
}
v1.getBufferSizeFor(valueCount) # failed, get error java.lang.IndexOutOfBoundsException: index: 15880, length: 4 (expected: range(0, 15880))
