    32 // Test that if a class's InnerClasses attribute contains a class that is not

    33 // accessible to the class with the attribute then an IllegalAccessError

    34 // exception should not get thrown as a result of the class accessing other

    35 // classes in the InnerClasses attribute.

    36 //

    37 // In this test, class InnerClassesTest has an InnerClasses attribute with two

    38 // entries.  One for inaccessable (non-public) class com/g/Base and class

    39 // con/g/Base$Builder.  And, one entry for classes com/n/InnerClassTest and

    40 // com/n/InnerClasses/Test$Foo.  The test accesses com/n/InnerClsses/Test$Foo

    41 // by calling getSimpleName().  This should not cause an IllegalAccessError

    42 // exception to get thrown.

    43 //

    44 //

    45 // This jasm code was generated from the following Java code.  The only

    46 // difference is that, in the jasm code, the order of the entries in the

    47 // InnerClasses attributes for class InnerClassesTest were switched.
