In JDK 1.2, setDefaultLightWeightPopupEnabled(false) does not
force nested JMenu's to heavy weight as it should. However
this works correctly in JDK1.1.7a (Swing 1.0.3 also known as
JFC 1.1). You can see this in the following example, try to
pick a "Steak" from the "Heavy Menu":

/*
 * This code based on from Amy Fowler's example. It adds
 * Nested JMenu's, which can not be seen under JDK 1.2 (bug) but work fine in JDK 1.1.7a

// Resize the JFrame so it is very small, and the missing "Steak"
// JMenu becomes heavy weight.
