By "latest", do you mean 20010503? The reason I ask is that Remy made
some changes yesterday that would have shown up in the 20010504 build, and
these changes fixed class reloading at least for the use case reported in
the bug report (i.e. load one of the example app servlets, then recompile
it). The changes were specifically in the code area you describe above.
