StringBuffer not expanding properly, appended text gets cut off

Question

I am trying to use a StringBuffer, but for some reason the String is being capped at 100 chars. For Example:
StringBuffer sb = new StringBuffer();
sb.append("This is a test ONE.");
sb.append("This is a test TWO.");
sb.append("This is a test THREE.");
sb.append("This is a test FOUR.");
sb.append("This is a test FIVE.");
sb.append("This is a test SIX.");
sb.append("This is a test SEVEN.");
sb.append("This is a test EIGHT.");
System.out.println(sb.toString());
When I call sb.toString(), the String returned is only 100 chars long. I could manually tell the sb to expand its size, but that really shouldn't be necessary.
Any clue what is going on here?

Answer 1

1) The terminal, console, etc. which is reporting
System.out is not working correctly.I am just using System.out as an example. When running the debugger the String object returned by sb.toString() is only 100 chars long.
Actually, if I step through with the debugger and examine the contents of the StringBuilder, this is what I can see:
sb.value = char[142] // Containing the characters as I append them
sb.count = 72 // Indicating the current length of the String stored in the StringBuffer
For some reason, when trying to append the String which sets the count over 100, the count variable increases but extra characters over 100 aren't actually stored into the value array.
The sb.append() methods internal call to String.getChars(0, len, value, count); is not working properly, although I'm not sure why this would happen.
2) Your not running the class you think you areDefinately running the java.lang.StringBuilder class.
