AWT

<has flashbacks>
The love monkey is spot on.
[edit] AWT - Abstract Windows Toolkit. A part of Java that developers use to create GUIs. It has been superseded by Swing. Interfaces still look awful though, and fall over often. IME, the point at which AWT/Swing uses native code is typically where problems occur. Prior to Java 1.4 I had the task of getting a load of Java code working on a server. Nightmare.
