test/jdk/tools/launcher/ToolsOpts.java

I don't understand how the change fixes the problem. IIUC the problem is 
that the test expects the output to consist of the command-line passed 
to the tool. Instead if it contains a Warning from the VM, it won't 
match and so we fail. The new code no longer uses a String[] and no 
longer assumes that output[i] == args[i], but it still searches the 
current "output" value for a match with one of the args. But that will 
still fail if what we actually have is a Warning. ?? I would have 
expected to see the Warning strings filtered out more directly.

The other test change seems reasonable.

Thanks,
David
