java.lang.Class.getMethods() returns not all inherited methods of interface.
The sample program ( see source below ) shows that for interface
org.w3c.dom.CDATASection the method returns only method splitText(int)
defined in direct superinterface org.w3c.dom.Text .
But the org.w3c.dom.Text inherits a lot of methods defined in superinterfaces.

This wrong behaviour is detected for all merlin builds starting from
jdk 1.4.0beta-build51.

The bug seems do not affect reflection of classes, interfaces only.
