[urgent] RFR: 8081470 com/sun/jdi tests are failing with "Error. failed to clean up files after test" with jtreg 4.1 b12

[Staffan Larsen]

Can I have a fast review of the following change that is currently blocking hotspot pushes in jprt. jtreg 4.1b12 adds stricter checking of @library tags. Some com/sun/jdi tests have @library clauses that are not needed. 

I do not intend to wait 24 hours before pushing this...
