Hi,
On writing tests for java.lang.instrument, I find it nice Harmony
launcher can accept parameter "-javaagent" currently. Look deep into
the launcher code, I find the parameter was really parsed by VM itself
currently.
And if I use J9VM, it can accept such parameter but ask for
"instrument.dll". As we know, Harmony naming convention use
"hyXXX.dll" as dll-file name. So vm fails to load lib here. However if
I copy the file "hyinstrument.dll" to "instrument.dll", J9VM load it
happily and pass my test on Instrument.
Great - Ill look into getting this fixed in the next VME so that it picks
up hyinstrument.dll when running with Harmony.
I do not know what does DRLVM or other VMs do here (I'd like to
hear if jvmti has been implemented in DRLVM).
So Instrument testcases can not be put to svn until this problem
is solved (or it'll break build!). I guess there are two ways here:
If it is holding you up, then the tests could always be checked into svn
and just excluded?

Oliver
1. to work around, add a line in build.xml, copy the file to
"instrument.dll", and wait for VM to get updated. Or we change
filename in build system forever?
2. I wonder if we can modify in launcher, parse the parameter and
pass the dll filename to VM?
Any suggestions?Thanks!
