RFR(S): 8075438 - [TESTBUG] Hotspot JTREG tests should use unique CDS archive names

Yes

The scratch directory will be JTwork\scratch and the file will end up there
when specifying '.'

Thanks,
Christian

Is this because jtreg is deleting the directory contents and windows is
preventing the file from being deleted, and so it interferes with the next
test?

When a test uses '.' for files what actual directory gets used for that? 
JTwork/scratch or JTwork/path/to/test ?

Thanks,
David
