/*
* This test is a pretty detailed test both of javac signature generation and classfile
* signature parsing. The first part of the test tests all the examples given in the
* second part of the test. Each example comes with one or two annotations, @Desc, @Sig,
* for the descriptor and signature of the annotated declaration. Annotations are
* provided whenever the annotated item is expected to have a corresponding value.
* Each annotation has two argument values. The first arg is the expected value of the
* descriptor/signature as found in the class file. This value is mostly for documentation
* purposes in reading the test. The second value is the rendering of the descriptor or
* signature using a custom Type visitor that explicitly includes an indication of the
* Type classes being used to represent the descriptor/signature. Thus we test
* that the descriptor/signature is being parsed into the expected type tree structure.
