Is it possible to find PDB (windows debugging info) for publishedjvm.dll?

[Thomas Stüfe]

Hm. In my experience, if you attempt to debug the VM at the level
Alexander intended, you usually do not get very far without
rebuilding, if only to get a fastdebug or slowdebug build. And if you
have the knowledge to debug the VM, building it should be not a big
hurdle.

Just my 5c..

(Should you attempt to rebuild on Windows, there are a number of
how-tos floating around. Here is mine:
