/**
* Bytecode processor for the default Servlet context integration.
*
*
* Transforms any javax.servlet.ServletContext implementation
* by registering servlet context instance (in the end of any constructor)
* and delegating all resource providing methods to JavaRebel.
*
*
* This can be used with servlet context implementations which are ready to provide resources
* already after the constructor call (no additional initialization method will be called afterwards).
