Declaration of an anonymous inner class with null keyword as a
parameter causes javac to throw sun.tools.java.CompilerError.

All JDK compilers from 1.1_Final thru 1.2C fail to compile
example "Test.java" (see source below), producing the following
compile-time exception:

> /export/ld14/java/dest/jdk1.2/solaris/bin/javac -d . Test.java
