Description Peter Wall CLA 2004-02-12 12:24:00 EST 
In J2SDK1.5beta1, StringBuffer nows extends AbstractStringBuilder, and this
class implements Appendable.  Appendable declares append(char) to throw
IOException, but the versions of this method in AbstractStringBuilder and
StringBuffer do not throw any exceptions.  This is permitted in the language
spec. - you may narrow but not widen the range of exceptions thrown.

The JDT compiler flags all uses of StringBuffer.append(char) demanding that it
be enclosed in a try-catch block or that the enclosing method is declared to
throw IOException.  This appears to be an incorrect interpretation of the
language spec.
