/**
* <b>These tests check binary weaving of code compiled with the 1.5 compiler. If you need to rebuild
* the class files then you will have to run tests/java5/bridgeMethods/build.xml.</b>
*
* <p>Bridge methods are generated when a type extends or implements a parameterized class or interface and
* type erasure changes the signature of any inherited method.
*
* <p>They impact AspectJ in two ways:
* <ol>
* <li>They exist as a method execution join point, and their 'body' exists as a set of new join points
* (although their body is normally coded simply to delegate to the method they are bridging too).
* <li> They create a potential call join point where a call can be made to the bridge method.
* </ol>
*
* <p>The principal things we have to do are avoid weaving their body and ignore their existence
* as a method execution join point. Their existence as a potential target for a call join point are
* more complicated. Although they exist in the code, a 1.5 compiler will prevent a call to them with
* an error like this:
*
* M.java:3: compareTo(Number) in Number cannot be applied to (java.lang.String)
* new Number(5).compareTo("abc");
*
* Our problem is that a Java 1.4 or earlier compiler will allow you to write calls to this bridge method
* and it will let them through.
