The following funny corner case breaks javac (ver. 1.2.2) compilation
to NullPointerException. If you try javac (ver 1.1.6) you'll get
"segmentation fault" failure.

Test example and javac diagnostics follow:
-------------------------------------------------------
novo35% cat test.java
package java.lang;

class Object {
    Object() {
        super();
    }
}

novo35% java -version
java version "1.2.2"
Classic VM (build JDK-1.2.2-C, green threads, sunwjit)
novo35% javac test.java
java.lang.NullPointerException
