Hi, Sian:
After some study, I found that it is necessary to treat j9
seperately,....mmm about security and vm library loader. I have not spot the
precise place.
I think we have first to get a wrapper jvm class like j9_13 derby gives
but not other standard wrapper class. Then we have to rewrite it java
command-line as "java" but not "j9". Am I all right?
Besides, it will be helpful if you can post your patch of Derby on the
http://wiki.apache.org/harmony/Apache_Derby.:)
Thank you.

Hi Leo,
I have previously run the Derby tests on Harmony with the IBM VME (see the
Wiki page - http://wiki.apache.org/harmony/Apache_Derby). I had to make
some changes to Derby to get it to run, but from reading the bug report it
sounds like you found a way round it too. If not then let me know and I
could send you a patch or post one here or something. I wasn't using
DRLVM
so I haven't seen the bug you're describing. Running with the IBM VME I
got
82% of the tests passing. I looked at some of the test failures but not
in
very much depth. However some of them seemed to be because the different
VMs had differently formatted output, so not necessarily a bug. I think
that's one of the reasons why the tests need to know what VM they are
using. The tests have different output files for different VMs that they
compare with the actual output for each test.
Just as a side point, several people have looked at applications in the
past
including myself and have posted the results on the Wiki (
http://wiki.apache.org/harmony/Application_Status). So if anyone is
having
a problem running a particular application it might be worth having a look
to check if someone has done it before. Or we could suggest that everyone
posts this kind of thing to the mailing list in future if that's more
likely
to be found.
Regards,
Sian
