MYJDI (MYJDI Youth Java Debug Implementation) is JDI implementation.

The Java Platform Debugger Architecture is structured as follows:

           Components                          Debugger Interfaces

                /    |--------------|
               /     |     VM       |
 debuggee ----(      |--------------|  <------- JVM TI - Java VM Tool Interface
               \     |   back-end   |
                \    |--------------|
                /           |

                \           |
                     |--------------|
                     | front-end    |

JPDA is a multi-tiered debugging architecture that allows tools developers to easily create debugger applications which run portably across platforms, virtual machine (VM) implementations and JDK versions.

JPDA consists of three layers:

• Java VM Tool Interface (JVM TI) - Defines the debugging services a VM provides.
• Java Debug Wire Protocol (JDWP) - Defines the communication between debuggee and debugger processes.
• Java Debug Interface (JDI) - Defines a high-level Java language interface which tool developers can easily use to write remote debugger applications.
