12. In the Java 2 SDK, abstract method drawString(AttributedCharacterIterator, 
int, int) has been added to class java.awt.Graphics as part of the 
Input Method Framework for use by the PersonalJava platform. It 
is expected that suclasses of Graphics in applications based 
on the 1.1 platform are rare. Any such subclasses that do exist, 
however, will need to provide an implementation of this new abstract method 
for use in conjunction with the 1.2 platform. [bug 4128205] 


The problem is that we want to be able to *run* the same .class files
on both 1.1 and 1.3. So no compile-time detection is satisfactory. Grr...
