III. Implementation plan

For promotion B we plan to deliver:

new Debugger Core API: support for integration of CPP debugger, and JSP debugger, sharing UI (List of Debugger Core API Requirements)
full integration with new Window System.

For promotion D we plan to deliver:

Java Debugger API: support for JSPand J2EE debugger
Full JSR45 support:
Full featured Java debugger: based on new Debugger Core APIs and Java Debugger APIs, all implementation and UI of Java Debugger must be rewritten to new APIs
Threads & CallStack filterring: support for filterring of code generated by server / precompiler (EJB)
Smart Stepping: support for filterring of code generated by server / precompiler (EJB)
Full JDK 1.5 support: generics, enumy, static imports, autoboxing / unboxing, varialble number of arguments
