RDB doesn't use any license. We can pick any license that is compatible
with Jikes RVM project or we can transfer the ownership of RDB to Jikes
RVM project. Currently there are two people working on RDB -- Matthias
and myself. We'll submit contributor statements. There are no files in
RDB that are based on files supplied by Mac OS X. We studied how GDB
controls an inferior process on Mac OS X and implemented our own IPC
procedures. There's no code borrowing or copying in any form.
Jikes RVM Linux build includes building RDB. In fact even now RDB can
be used on Linux as RVM boot image viewer. The missing part is the code
that interacts with a running RVM process. We plan to implement this,
but we can't guarantee how soon this will be done.
c) We currently don't have automated tests for testing RDB, but I believe it is important to add such tests.
d) We synchronize the current RDB repository with the commits in the
official RVM repository. The integration process should be no more
complex than applying a patch that we'll submit. We'll definitely
continue working on RDB as we plan to add more features and we're
committed to fixing the defects.
