nsk/jdi tests unloading classes are incompatible with NoPermGen

      Description

      A couple of tests under nsk/jdi rely on exhausting PermGen to force class unloading. Now that PermGen is no more, this technique instead exhausts native memory (atleast without -XX:MaxMetaspaceSize) leading to both OOM errors and high load on test machines due to intensive swapping.

      Affected tests:
