-----------------------------------

             Summary: parser.java stack expansion probably not as intended
                 Key: AVRO-1641
                 URL: https://issues.apache.org/jira/browse/AVRO-1641
             Project: Avro
          Issue Type: Bug
    Affects Versions: 1.7.7, 1.8.0
            Reporter: Zoltan Farkas
            Priority: Minor


at Parser.java line 65 (https://github.com/apache/avro/blob/trunk/lang/java/avro/src/main/java/org/apache/avro/io/parsing/Parser.java#L65): 

 private void expandStack() {
    stack = Arrays.copyOf(stack, stack.length+Math.max(stack.length,1024));
  }

should probably be:

private void expandStack() {
    stack = Arrays.copyOf(stack, stack.length+Math.min(stack.length,1024));
  }

This expansion probably is intended to grow exponentially up to 1024, and not exponentially after 1024...
