when I call ArrowStreamReader.vectorSchemaRoot(),

`The messageLength is negative, code is in MessageSerializer.java`
**messageLength = MessageSerializer.bytesToInt(buffer.array())**;\``
`and error is raised in `
**ByteBuffer messageBuffer = ByteBuffer.allocate(messageLength)**;\``
I tried to use minimal reproduce code to reproduce the error but I could not
reproduce it. So **any ideas that when can it get negative messageLength**?
This error occurs occasionally in my program.
