[drlvm] An easy task for a DRLVM newby: fix -verbose:class
Hi,
as discussed in HARMONY-1847, -verbose:class currently does not produce output
which is reasonable to expect.
For example, running HelloWorld on JRockit 1.5 produces something like
the below text (only several lines provided).
The right way to fix is to put logging lines in the class loading code,
like
INFO2("class", "[load] opened zip " << zip_file_name);
INFO2 is a macro available by
#include <cxxlog.h>
First argument is the logging category "class",
the second argument is the iostream-style printed message,
concatenated together with operator <<.
The task will take some reading through enhanced/drlvm/trunk/vm/vmcore/src/class_support/*.c
Any undertakers?

BTW, you asked several days ago what would be the content of our wiki page.
The list with easy but useful tasks for newbies can be a good idea :)

For the record, an "undertaker" is a person that runs a funeral home. I
think you meant "takers" :)
This is a good task. Feel free to add it to JIRA to make it easy for
someone to find.
