The Java Application Programming Interface, Volume 1, Core Packages,
says for forName() method (p. 16):
"PARAMETERS:
className: the fully qualified name of the desired class."

÷ The Java Virtual Machine Specification, chapter 2.7.9 Fully Qualified Names, says (p. 23):
"Every package, class, interface, array type, and primitive type has a fully qualified
name. It follows that every type except the null type has a fully qualified name.
- The fully qualified name of a primitive type is the keyword for that primitive type, namely boolean, char, byte, short, int, long, float, or double.
- The fully qualified name of a named package that is not a subpackage of a named package is its simple name.
- The fully qualified name of a named package that is a subpackage of another named package consists of the fully qualified name of the containing package followed by "." followed by the simple (member) name of the subpackage.
- The fully qualified name of a class or interface that is declared in an unnamed package is the simple name of the class or interface.
- The fully qualified name of a class or interface that is declared in a named package consists of the fully qualified name of the package followed by "." followed by the simple name of the class or interface.
- The fully qualified name of an array type consists of the fully qualified name of the component type of the array type followed by "[]".
"

So, the JCK execution00301 test below uses invalid fully qualified class
name (javasoft.sqe.tests.vm/concepts.execution003.execution00301.execution00301a
                           ^ erroneous symbol
in execution00301.java) in the java.lang.Class.forName() invocation.
However, jdk1.2Z does not discover it:

novo7% setenv CLASSPATH /export/home/JAVA/workdir/classes:/export/home/JAVA/sqe_my/harness_release/classes
novo7% /export/ld14/java/dest/jdk1.2Z/solaris/bin/java -verify javasoft.sqe.tests.vm.concepts.execution003.execution00301.execution00301
novo7% echo $status
97
novo7%

The test works fine for jdk1.1.*:

novo7% setenv CLASSPATH /export/home/JAVA/workdir/classes:/export/home/JAVA/sqe_my/harness_release/classes
novo7% /export/ld14/java/dest/jdk1.1.1/solaris/bin/java -verify javasoft.sqe.tests.vm.concepts.execution003.execution00301.execution00301
java.lang.IllegalArgumentException: javasoft.sqe.tests.vm/concepts.execution003.execution00301.execution00301a
novo7% echo $status
95
novo7% /export/ld14/java/dest/jdk1.1.6/solaris/bin/java -verify javasoft.sqe.tests.vm.concepts.execution003.execution00301.execution00301
java.lang.IllegalArgumentException: javasoft.sqe.tests.vm/concepts.execution003.execution00301.execution00301a
novo7% echo $status
95
