StringBuffer.getChars throws an Exception if
srcBegin >= count; that is bogus when count == 0.
getChars should only perform the checks in the
language spec, namely:

     srcBegin is negative
     srcBegin is greater than srcEnd
     srcEnd is greater than the length of this String
     dstBegin is negative
     dstBegin+(srcEnd-srcBegin) is larger than dst.length

This is JLS section 20.13.11

The code for StringBuffer.getChars() looks like this:
 public synchronized void getChars(int srcBegin, int srcEnd, char dst[], int dstBegin) {
if ((srcBegin < 0) || (srcBegin >= count)) {
throw new StringIndexOutOfBoundsException(srcBegin);
...

So clearly we go beyond just srcBegin > srcEnd or srcBegin > srcLength as stated in the JLS.
