... which is necessary for dynamically loaded classes anyway.
(Though they could conceptually be handled like dynamically
loaded shared libraries.)
There is some old probably-bit-rotted-and-disabled code in
gdb to grovel through the metadata. When using a JIT
you could in principle debug JIT'ed Java code just the same
as regular Java code, as long as the JIT'er and gdb can
communicate about the new classes..
