This is long overdue, thank you!

With your changes it means that these tests will actually test what we 
think they are testing, eg: "jtreg -vmoption:-client" will actually use 
the client VM to give a simple example. Also it means that finally we 
can control the heap size of these tests, really important when running 
tests concurrently. Finally it means that we can do code coverage and 
use other tool agents with the shell tests, impossible until now. 
Clearly we need to try to replace as many of these shell tests as 
possible over time but that is a much longer term effort.

I skimmed over the patch file and nothing obvious jumped out.  The main 
thing that I looked for was tests that were specifying VM options that 
might conflict with options passed into jtreg. A few minor comments:

- it's okay to ignore java/nio/Buffer/genBasic.sh and 
java/nio/Buffer/genCopyDirectMemory.sh as they are used to generate the 
tests and so aren't used in the actual test execution.

- java/nio/channels/AsynchronousChannelGroup/run_any_task.sh, I see this 
is using -XX:-UseVMInterruptibleIO. This isn't needed any more so you 
can remove it while you are there.

One final point is that jdk/test/Makefile will likely require changes 
too but that is separate to your changes.
