+<intro id="bcimodules" label="Bytecode Instrumentation of code in modules">
+ Agents that instrument code in named modules may need to arrange for those
+ modules to read other modules. If code is instrumented to invoke a method
+ in a support class in another module, then the module of the instrumented
+ code should read the module of the supporting class. Furthermore, the
+ supporting class will only be accessible to the instrumented code if
+ it is <code>public</code> and in a package that is exported by its module.
+ Agents can use the JNI functions <code>CanReadModule</code> and
+ <code>AddModuleReads</code> to test and update a module to read another.
+ <p/>
+ As an aid to agents that deploy supporting classes on the search path of
+ the bootstrap class loader, or the search path of the class loader that
+ loads the main class, the Java virtual machine arranges for the module
+ of classes transformed by the <eventlink id="ClassFileLoadHook"/> event to
+ read the unnamed module of both class loaders.
