the reason I had to this change is that jtreg doesn't handle `"` in any special way, so `gf08t003
nsk.jvmti.scenarios.general_functions.GF08.gf08t003 "Registering JNI native method" jni` is passed to `gf08t` as
[`gf08t003`, `nsk.jvmti.scenarios.general_functions.GF08.gf08t003`, `"Registering`, `JNI`, `native`, `method"`, `jni`].
the way I fixed that was by changing the order of `phrase`, `verboseType`, so `verboseType` is now 2nd arg, and
`phrase` 3rd and the rest of args joined.

the alternative way would be to teach `gf08t` about `"` and make it join arguments until it gets an even number of `"`
and remove them, this, from my PoV, would be a bit more confusing. if you however are of string opinion here, I can go
w/ that alternative (or any other if you have more suggestions)
