Prior to jdk1.2beta3 the following code produced:

java pkg2.TestExtendedClass
Testing Extended Class

using jdk1.2beta3:

java pkg2.TestExtendedClass
java.lang.IllegalAccessError: try to access class pkg1/PackagePrivateClass from class pkg2/TestExtendedClass
        at pkg2.TestExtendedClass.<init>(TestExtendedClass.java:12)
        at pkg2.TestExtendedClass.main(TestExtendedClass.java:22)

In your test directory, place the three files at these locations:
pkg1/PackagePrivateClass.java
pkg1/ExtendedClass.java
pkg2/TestExtendedClass.java

Compile and run with the test directory on your classpath, and you get the above Exception.
